Answer: 20% : 100/3% : 140/3%

Step-by-step explanation:

Let the ratio be 3x , 5x and 7x.

SInce these ratios are to converted into ratio of percentages , they should add up to 100%

ie, 3x + 5x + 7x = 100

ie, 15x = 100

ie, x = 100/15

      = 20/3

ie, 3x = 3 × 20/3 = 20%

5x = 5 × 20/3 = 100/3%

7x = 7 × 20/3 = 140/3%
