Maths Quiz - Ratio 2 (Medium) (Answers)

Seventy photographs are to be displayed in a gallery. If the ratio of portrait pictures to landscape pictures has to be 3:4, how many portrait pictures and landscape pictures have to be selected?

[x]	30 portrait pictures and 40 landscape pictures
[ ]	35 portrait pictures and 35 landscape pictures
[ ]	25 portrait pictures and 45 landscape pictures
[ ]	45 portrait pictures and 25 landscape pictures

3 + 4 = 7 ? the fractional parts are ³?₇ × 70 = 30 portrait pictures and ⁴?₇ × 70 = 40 landscape pictures. CHECK 30:40 = 3:4 (dividing by 10). Your answer MUST preserve (keep) the same ratio

Farmer Bull has 20 cows. How many sheep does Farmer Bull have if the ratio of cows to sheep is 5:6?

[ ]	22
[x]	24
[ ]	26
[ ]	28

5:6 = 1:1.2 (dividing by 5). This means that there is 1 cow for every 1.2 sheep ? there are 1.2 as many sheep as there are cows = 1.2 × 20 = 24. CHECK 20:24 = 1:1.2 (dividing by 20). Your answer MUST preserve (keep) the same ratio. ALWAYS try to REDUCE your ratios so as to get a '1' in one of the terms of the ratio. Incidentally, 20 + 24 = 44 animals in all!

The ratio of cheese sandwiches to ham sandwiches is 7:5. If there are 36 sandwiches in all, how many ham sandwiches are there?

[ ]	21
[ ]	18
[x]	15
[ ]	12

7 + 5 = 12 so ⁷?₁₂ of the sandwiches are cheese and ⁵?₁₂ are ham. 36 ÷ 12 = 3 so each unit in the ratio represents 3 sandwiches. 3 x 7 = 21 and 3 x 5 = 15. There are 21 cheese sandwiches and 15 ham sandwiches

The ratio of red roses to white roses is 7:9. What fraction of the roses are white?

[ ]	⁹⁄₈
[ ]	⁷⁄₁₆
[ ]	⁷⁄₈
[x]	⁹⁄₁₆

How else can the ratio 9:24 be written?

[x]	3:8
[ ]	4:12
[ ]	1:3
[ ]	18:46

9:24 = 3:8 (dividing by 3)

The following ratios show the ratio of wins to defeats for four football teams. If all four teams have played the same number of games, which team has won the most often?

[ ]	1:1
[ ]	9:10
[x]	21:17
[ ]	14:24

1:1 represents an equal number of wins and defeats. 9:10 and 14:24 both represent fewer wins than defeats. Only 21:17 represents more games won than lost

⁴⁄₇ of the children in a class are girls. What is the ratio of girls to boys in the class?

[ ]	3:4
[x]	4:3
[ ]	4:7
[ ]	7:4

If ⁴?₇ of the children in a class are girls, then ³?₇ of the children must be boys

Which of the following is not a way of expressing the ratio 5:6?

[ ]	10:12
[ ]	25:30
[ ]	45:54
[x]	60:78

10:12 is the same as 5:6 (multiply by 2), 25:30 is the same as 5:6 (multiply by 5), 45:54 is the same as 5:6 (multiply by 9). 60:78 is NOT the same as 5:6 – the 5 has been multiplied by 12 but the 6 has been multiplied by 13
