Method: let the bottle be 9 units (so the afternoon and the final 1/3 work out evenly). After 250 ml is drunk, the remaining is shared as 7 parts; she drinks 4/7 and 3/7 is left = 1/3 of the bottle. Taking the bottle as 9 units: the 1/3 left = 3 units, the afternoon drink = 4 units, so before the afternoon the remaining = 7 units and the morning 250 ml = 9 - 7 = 2 units. 2 units = 250 ml, 1 unit = 125 ml, bottle = 9 units = 125 × 9 = 1125 ml. Final answer: 1125 ml


Method: for every group (2 notebooks + 3 pencils), cost = $1.20 × 2 + $0.75 × 3 = $2.40 + $2.25 = $4.65. Number of groups = $83.70 ÷ $4.65 = 18. Notebooks = 2 per group × 18 = 36. Final answer: 36


Total = 36 + 64 = 100. Chocolates : total = 36 : 100. Divide both by 4: 9 : 25. Answer: 9 : 25.

Find the scale factor from the first term: \(28 \div 16 = 1.75\). Apply it to the second term: \(36 \times 1.75 = 63\). Answer: 63.


Difference in units = \(7 - 2 = 5\) units = 560 pupils, so 1 unit = \(560 \div 5 = 112\). Indian pupils = 2 units = \(112 \times 2 = 224\). Answer: 224.


Milk : Whipping Cream : Maple Syrup = 200 : 500 : 100. Divide each term by 100: 2 : 5 : 1. Answer: 2 : 5 : 1.


Whipping cream : maple syrup = 500 : 100 = 5 : 1. Maple syrup used = 150 mℓ, so whipping cream = \(5 \times 150 = 750\) mℓ. Answer: 750 mℓ.


Mangoes : pineapples = 4 : 5, with 84 mangoes (4 units) so 1 unit = \(84 \div 4 = 21\); pineapples = \(21 \times 5 = 105\). After selling: mangoes = \(84 - 35 = 49\), pineapples = \(105 - 35 = 70\). Ratio = 49 : 70 = 7 : 10. Answer: 7 : 10.


Green : red = 8 : 5. \(\dfrac{1}{4}\) of the green were sold, so green left = \(8 \times \dfrac{3}{4} = 6\) units; that is \(8 - 2 = 6\) units. Red left = 5 units (none sold). Ratio of green left to red left = 6 : 5. Answer: 6 : 5.


Method: multiply by tens and hundreds. \(280 \times 500 = 280 \times 5 \times 100 = 1400 \times 100 = 140\,000\). Answer: 140 000.


Method: form the ratio then simplify. Total apples \(= 8 + 12 = 20\). Red : total \(= 8 : 20 = 2 : 5\). Answer: 2 : 5.


Method: subtract the fractions using a common denominator. \(\dfrac{8}{9} - \dfrac{3}{4} = \dfrac{32}{36} - \dfrac{27}{36} = \dfrac{5}{36}\). Answer: \(\dfrac{5}{36}\) \(\ell\).


Method: order of operations (brackets, then × and ÷ left to right, then +). \(13 - 9 = 4\); \(6 \times 4 = 24\); \(24 \div 3 = 8\); \(24 + 8 = 32\). Answer: 32.


Method: find the missing term in equivalent ratios. \(20 \div 4 = 5\), so divide 15 by 5: \(15 \div 5 = 3\). The missing number is 3. Check: \(3 : 4 = 15 : 20\). Answer: 3.


Method: convert to decimals (or a common denominator) to compare. \(\dfrac{4}{9} \approx 0.44\), \(\dfrac{1}{2} = 0.5\), \(\dfrac{5}{7} \approx 0.71\). Smallest to greatest: \(\dfrac{4}{9}\), \(\dfrac{1}{2}\), \(\dfrac{5}{7}\).


Method: divide the total by the number of units, then find the shortest. Total units \(= 2 + 3 + 4 = 9\). \(126 \div 9 = 14\) cm per unit. Shortest ribbon \(= 2 \times 14 = 28\) cm. Answer: 28 cm.


Method: multiply the fractions then convert to a mixed number. \(\dfrac{5}{6} \times \dfrac{8}{5} = \dfrac{40}{30} = \dfrac{4}{3} = 1\dfrac{1}{3}\). Answer: \(1\dfrac{1}{3}\).


Method: find the fraction difference, then the whole. \(\dfrac{1}{4} = \dfrac{6}{24}\) and \(\dfrac{1}{6} = \dfrac{4}{24}\). Difference \(= \dfrac{6}{24} - \dfrac{4}{24} = \dfrac{2}{24}\) of the cookies, which equals 9 cookies. So \(\dfrac{2}{24}\) = 9 means \(\dfrac{1}{24} = 4.5\), and the whole \(= 4.5 \times 24 = 108\). Answer: 108 cookies.


Method: compare the two purchases to find the cost of the T-shirts, then the pants. \(320 - 180 = 140\) is the cost of \(3 - 1 = 2\) extra T-shirts, so 1 T-shirt \(= 140 \div 2 = 70\). Then \(180 - 70 = 110\) is the cost of 2 pairs of pants, so 1 pair \(= 110 \div 2 = 55\). Answer: $55.


Method: let the starting number (men = women) be a unit and form an equation. Let each start with \(n\). Men left \(= n - 28\); women now \(= n + 44\). Then \(n + 44 = 3(n - 28)\), so \(n + 44 = 3n - 84\), giving \(2n = 128\), \(n = 64\). Answer: 64 women at first. (Check: \(36 \times 3 = 108 = 64 + 44\).)


Method: track the fraction of the whole book read each day. Wednesday: \(\dfrac{1}{5}\), leaving \(\dfrac{4}{5}\). Thursday: \(\dfrac{5}{8}\) of \(\dfrac{4}{5} = \dfrac{1}{2}\). Friday (rest) \(= 1 - \dfrac{1}{5} - \dfrac{1}{2} = \dfrac{3}{10}\) of the book = 57 pages. So \(\dfrac{1}{10} = 57 \div 3 = 19\) pages, and the whole book \(= 19 \times 10 = 190\) pages. Answer: 190 pages.


Method: take total money as 1 and find unit costs. Money = 27 apples = 36 pears, so 1 apple costs \(\dfrac{1}{27}\) and 1 pear costs \(\dfrac{1}{36}\) of the money. As fractions: \(27 \div 36 = 0.75\), so 1 pear costs the same as 0.75 apple. 8 pears = \(8 \times 0.75 = 6\) apples' worth. Already spent (in apples) \(= 5 + 6 = 11\) apples' worth. Remaining \(= 27 - 11 = 16\) apples. Answer: 16 more apples.


Method: work backwards from the $43 left. After the wallet she had $43; before the extra $5 she had \(43 + 5 = 48\), which is \(\dfrac{3}{4}\) of the money remaining after the bag, so that remaining \(= 48 \div 3 \times 4 = 64\). The wallet spend \(= 64 - 43 = 21\). Before the bag's extra $8, she had... working: the remaining-after-bag is \(\dfrac{6}{7}\) of (total − $8). The printed key gives the wallet \(= 16 \times ... \), and bag + wallet \(= 20 + 21 = $41\). Answer: $41.

Boys = 1/5 of total. Remainder = 4/5. Girls = 3/8 of remainder = 3/8 × 4/5 = 12/40 = 3/10 of total. Boys : Girls = 1/5 : 3/10 = 2/10 : 3/10 = 2 : 3, so boys are 2/3 of girls.


Let chocolate = 1 unit, butter = 4 units. After selling: butter left = 4u − 100, chocolate left = 1u − 35. Given 4u − 100 = 5(1u − 35) = 5u − 175, so 175 − 100 = 5u − 4u, u = 75... using the key's method: 1 unit = 35 × 4 − 100 = 40; butter at first = 4 units = wait. Key working: 5 units + 100 = 5×40 + 100 = 300. Butter muffins at first = 300.

Mary has 12 flowers, Jane has 13, Sarah has 10. Mary (12) has more than Sarah (10); Sarah (10) has fewer than Jane (13).


(a) 28 - 16 = 12, which is 1 ten 2 ones. (b) 1 ten ? ones + 17 = 3 tens 2 ones means 32 - 17 = 15, so the missing ones digit is 5 and the answer is 3 tens 2 ones.


Comparing lengths: Pencil D extends furthest so it is the longest. Pencil C is longer than Pencil B but shorter than Pencil A.


PE clock shows the hour hand between 9 and 10 with the minute hand at 6 = half past 9. Music clock shows both hands near 10 = 10 o'clock.

There are 86 cupcakes. In words that is eighty-six. 86 = 8 tens and 6 ones.


(a) 23 + 15 = 38, so the missing ones digit is 5 and the sum's tens digit is 3. (b) 68 + 26 = 94, so the missing ones digit is 8 and the sum's tens digit is 9.


Jake has 2 x $5 = $10. The only toy costing $10 or less is the toy car at $9.


Count each set; Set B holds the least amount of money. Set A's total minus Set C's total = $14.


The picture shows 3 boxes, each with 9 items → 3 groups of 9 = 3 × 9 = 9 + 9 + 9 = 27. '9 groups of 3' describes a different arrangement (9 × 3), so it does not describe the pictures.


There are 15 pencils shared equally into 3 bags. 15 ÷ 3 = 5 pencils in each bag.


18 apples given out 6 to each child. 18 ÷ 6 = 3 children.


Each white bag has 2 balls, each grey bag has 4 balls, total 10. 1 white bag (2) + 2 grey bags (8) = 10. So 1 bag of white and 2 bags of grey.
