Answer 2

Answer:

50 % , 40 % & 14 %

Step-by-step explanation:

1. 15 : 30

Dividing by 3 we get, 5 : 10, dividing by 5 we get 1 : 2.

so its 50 %

2. 2 : 5

2 : 4 can be written as 2 / 5 = 0.4;

Multiplied 0.4 by 100, 0.4 × 100 = 40, so the percentage of ratio 2 : 4 is 40%.

3. 7 : 50

7 : 50 can be written as 7 / 50 = 0.14;

Multiplied 0.14 by 100, 0.14 × 100 = 14, so the percentage of ratio 7 : 50 is 14%
