Perimeter = 2(L + B) with L = 2B, so 6B = 54, B = 9 m, L = 18 m. Area = 18 x 9 = 162 m².


Total = 5 units = 685, so 1 unit (Mrs Lim) = 685 ÷ 5 = 137. Mrs Chan baked 3 more units = 3 x 137 = 411 more muffins.


Packed = 46 x 8 = 368. At first = 368 + 37 = 405 stickers.


June needs 3 x 78 = 234 seashells. She must collect 234 - 42 = 192 more.


Decreasing order means largest to smallest. Compare thousands then hundreds: 3692 > 3687 > 1069.


(a) The pattern increases by 10 each time, so after 6194 comes 6204. (b) The pattern alternates +1 then +1000: 2502 + 1 = 2503.


12 free doughnuts ÷ 2 doughnuts per set = 6 sets. Each set needs 8 cupcakes, so 6 × 8 = 48 cupcakes.


Tuesday = 2328 - 519 = 1809 customers. Both days = 2328 + 1809 = 4137 customers.


All start with 8. Compare hundreds: 8769 and 8796 have 7 hundreds (smallest). Then compare tens: 6 < 9, so 8769 is smallest.


2501 has 2 thousands (smallest). 3127 and 3210 both have 3 thousands; 3127 has 1 hundred vs 3210's 2 hundreds, so 3127 < 3210. Order: 2501, 3127, 3210.


(a) For the greatest odd number the ones digit must be odd; among 2,5,7 use largest digits first: 7 and 2 in front, odd 5 last -> 725. (b) For the smallest even number the ones digit must be even; cannot start with 0, so 2 hundreds, 0 tens, even ones 5? 5 is odd, so use 0 ones -> 250.


February is $253 less than January, so January = 799 + 253 = 1052. Altogether = 1052 + 799 = 1851.


813 ÷ 6 = 135 remainder 3, so it cannot be divided by 6 exactly. (354, 432, 768 all divide exactly.)


Together they form 6 equal units (Rick 1, Billy 5). 162 ÷ 6 = 27 = Rick. Billy = 5 × 27 = 135.


260 ÷ 7 = 37 remainder 1, leaving 1 extra pencil. To make another full box of 7 he needs 7 − 1 = 6 more pencils.


Cindy: 6.23 to 7.10 = 47 min. Kaixin: 6.46 to 7.23 = 37 min. Kaixin is shorter by 47 - 37 = 10 min.

Total seats = 10 x 9 = 90. Occupied = 90 - 2 = 88 seats.


Sandra has 5 x 9 = 45 stamps; Ravi has 9. Together = 45 + 9 = 54, so each should have 54 div 2 = 27. Sandra must give 45 - 27 = 18 stamps. (Equivalently, the difference is 45 - 9 = 36, and half of that, 18, is transferred.)


In 4985 the digits from the right are: 5 ones, 8 tens, 9 hundreds, 4 thousands. So the digit in the thousands place is 4.


Expanded form of 7854 is 7000 + 800 + 50 + 4. The tens digit is 5, worth 50. So the missing number is 50.


Compare each: 101 < 110 (false); 970 > 410 (false); 8420 > 8220 (false); 7052 > 7025 because the tens digit 5 > 2 (true). So option 4 is correct.


Eight thousand = 8000, and five = 5 ones. There are no hundreds or tens, so write 0 in those places: 8005.


The numbers increase by 4 each time (283, 287, 291, 295). Working backwards: 283 - 4 = 279 and 279 - 4 = 275. So the missing numbers are 275 and 279.


They started with the same amount. Hannah had less left ($0.40 vs $1.20), so her item (the burger) cost more. The difference in money left is $1.20 - $0.40 = $0.80, so the burger cost $0.80 more.

In the hall, there were 465 grey chairs and some blue chairs at first. Another 45 grey chairs were added. In the end, there were 5 times as many grey chairs as blue chairs. (a) How many blue chairs were there? (b) How many chairs were there altogether in the hall at first? <br>(a) <input type="text" id="input_0" class="fill-blank-input" placeholder="?" />   (b) <input type="text" id="input_1" class="fill-blank-input" placeholder="?" />

(a) After adding 45, grey chairs = 465 + 45 = 510. Grey is 5 times the blue, so 5 units = 510, meaning 1 unit (blue) = 510 ÷ 5 = 102 blue chairs. The number of blue chairs did not change. (b) At first there were 465 grey + 102 blue = 567 chairs altogether.


Beth, Katie and Pamela had some cards. Beth had 69 fewer cards than Katie. Beth and Katie had a total of 277 cards. Pamela had as many cards as Beth. (a) How many cards did Pamela have?

How many more cards did Katie have than Pamela in the end? <br>(a) <input type="text" id="input_0" class="fill-blank-input" placeholder="?" />   (b) <input type="text" id="input_1" class="fill-blank-input" placeholder="?" />

(a) Beth + Katie = 277, and Beth is 69 fewer than Katie. Remove the difference: 277 - 69 = 208, which is 2 equal parts (2 x Beth). So Beth = 208 ÷ 2 = 104. Pamela has as many as Beth, so Pamela = 104. (b) Katie = 104 + 69 = 173. After Pamela gives 41 to Katie: Katie = 173 + 41 = 214, Pamela = 104 - 41 = 63. Difference = 214 - 63 = 151. (Equivalently, the gap changes by 2 x 41 = 82, and Katie was already 69 ahead of Pamela: 69 + 82 = 151.)

Remove the 6-year difference from the total: 54 - 6 = 48 is twice Lee Ying's age, so Lee Ying = 48 / 2 = 24. Malik is 6 years older: 24 + 6 = 30.


Which of the following fractions is greater than 1/2?

A fraction exceeds 1/2 when the numerator is more than half the denominator. 5/9 > 4.5/9 = 1/2. The others are 1/2 or less (2/5, 3/7 less; 4/8 equals 1/2). Answer key: 4.


What is the missing fraction in the box? 6/10 + [box] = 1

1 - 6/10 = 4/10 = 2/5. So the missing fraction is 2/5. Answer key: 1.


For unit-type fractions with equal numerator, the smaller denominator is the larger fraction, so 1/8 > 1/11 is true. 2/9 < 5/9; 5/6 > 2/3; 3/4 = 9/12 not 6/12. Answer key: 3.


Arrange the following fractions in order. Begin with the greatest. 3/8, 1/4, 5/10 <input type="text" id="input_0" class="fill-blank-input" placeholder="?" />, <input type="text" id="input_1" class="fill-blank-input" placeholder="?" />, <input type="text" id="input_2" class="fill-blank-input" placeholder="?" />


5 chairs cost as much as 3 tables. A table cost $90. What is the cost of 1 chair? <input type="text" id="input_0" class="fill-blank-input" placeholder="?" />
