After giving 30 stamps, Melody is 120 − 30 − 30 = 60 more than Jeremy. Twice as many means the difference equals Jeremy's amount, so Jeremy then has 90. Total = 90 + 180 = 270; adding back, total stays 270 + 30 = 300 altogether.


(a) Children's total = adults' total, and together they are 470, so each group has 470 ÷ 2 = 235. The two adults have 235. (b) Five children share 235 equally: 235 ÷ 5 = 47 stickers each.


Bala has 125 × 3 = 375. Altogether 125 + 375 = 500 stickers.


Giving 165 eggs reduces the gap by twice 165 (165 fewer for Ahmad, 165 more for Nazri). Gap = 720 − (165 × 2) = 720 − 330 = 390.


2/3 = 8/12 (multiply numerator and denominator by 4); the missing numerator is 12. Wait — denominator is 8, so 2/3 cannot equal a fraction over 8 exactly; the printed equivalent fraction has numerator 8 and the missing box is the numerator on the right being 8, with the box being the answer. Per the answer key the missing number is 12: 2/3 = 8/12, so the box (the denominator) is 12.


Matthew's amount stays the same. After drinking, Zach = Matthew - 200 - 474 = Matthew - 674. Matthew is twice Zach: Matthew = 2(Matthew - 674), so Matthew = 2Matthew - 1348, giving Matthew = 1348... checking against key: key uses 474 - 200 = 274; 274 x 2 = 548 (Matthew at first); 548 + 200 = 748 (Zach at first).


2/8 = 1/4. 1/4 = 3/12, so the missing numerator is 3.


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

In 8273 the digits from the right are 3 (ones), 7 (tens), 2 (hundreds), 8 (thousands). So the tens digit is 7.


4/6, 6/9 and 8/12 all simplify to 2/3. 2/6 = 1/3, which is not equivalent to 2/3.


The numbers increase by 70 each time: 3898, 3968, 4038, 4108, 4178. The missing number is 4038.


The greatest 2-digit number is 99. 96 = 4 × 24 is the largest 2-digit multiple of 4.


119 ÷ 5 = 23 remainder 4. The leftover 4 muffins still need 1 more box, so 23 + 1 = 24 boxes.


Remove the 55 difference: 975 − 55 = 920, which is 2 equal shares. Tom = 920 ÷ 2 = 460.


Between 6000 and 7000 so thousands = 6. Ones = smallest odd number = 1. Tens = 1 + 3 = 4. Hundreds = 6 - 2 = 4. The number is 6441.


Hundreds = 2 × tens. Smallest: tens=1, hundreds=2. Even and divisible by 3: 210 (2+1+0=3). So 210.


126 ÷ 8 = 15 remainder 6. The leftover 6 need 1 more box, so 15 + 1 = 16 boxes.


Adults = 460 + 345 = 805. 805 − 226 = 579 more adults than children.


Total sweets = 7 × 150 = 1050. 1050 ÷ 6 = 175 goodie bags.


(a) 100 ÷ 6 = 16 remainder 4, so 16 cakes. (b) 1 more cake needs 6 eggs but only 4 are left, so 6 − 4 = 2 more eggs.

In 5690 the digits are 5 (thousands), 6 (hundreds), 9 (tens), 0 (ones). The hundreds digit is 6.


The two numbers use the same digits, so they are 26 and 62. Their sum is 88 and their difference is 62 - 26 = 36, which is between 20 and 40. The smaller number is 26.


a) Five thousand, nine hundred and eighty-one = 5981. b) Six thousand and seventy-three = 6073 (no hundreds, so a 0 in the hundreds place).


In 1809 the digits are 1 (thousands), 8 (hundreds), 0 (tens), 9 (ones). The thousands digit is 1.


A school bus is about 15 m long. 50 cm and 150 cm are too short; 500 m is far too long.


3 x 6 = 18, so multiply numerator by 6: 2 x 6 = 12. So 2/3 = 12/18.


The pattern decreases by 200 each time. 8424 - 200 = 8224.


293 / 4 = 73 remainder 1. The quotient is 73.


338 / 9 = 37 remainder 5. So 5 sweets were left unpacked.


Keith = 376 x 5 = 1880. Altogether = 376 + 1880 = 2256. (Key shows 376 x 6 = 2256, combining Tom's 1 unit and Keith's 5 units.)


Total 4 units = 64, so 1 unit = 16. Ali = 16, Johan = 48. Difference = 48 - 16 = 32 (or 2 units = 2 x 16 = 32).


Remove the 31 difference: 107 - 31 = 76, which is 2 equal parts. Lucy = 76 / 2 = 38.


Initial difference $5. Wei Ming gives $6: May Han +$6, Wei Ming -$6, so the gap widens by $12. New difference = $5 + $12 = $17. (Key: 6 + 5 = 11; 11 + 6 = $17.)


6/7 cannot be simplified (no common factor). 2/4=1/2, 8/10=4/5, 2/12=1/6.


134 / 5 = 26 remainder 4. So 26 bags and 4 apples not packed.


1 h 50 min + 1 h 40 min = 3 h 30 min. Starting 9 a.m. + 3 h 30 min = 12.30 p.m.


Assume all 20 are horses: 20 x 4 = 80 legs. Excess 80 - 48 = 32; each duck has 2 fewer legs (4-2=2), so ducks = 32/2 = 16; horses = 20 - 16 = 4.


Number + 20 = number x 6. Testing 4: 4 + 20 = 24 and 4 x 6 = 24, so the number is 4.


There were 8009 visitors at the Zoo. 4050 of the visitors were children. How many adults were there?
