• D. 15:3

Answer 1

The correct option is C

3:5

To convert fractional ratio into whole number ratio, we need to the follow the steps as below:

Step I: Find the least common multiple (L. C. M.) of the denominators :-

Denominators are 5 and 3

LCM of denominators = $5\times 3$ = 15

Step II: Multiply each term of the ratio by the least common multiple (L. C. M.):-

$\frac{1}{5}\times 15:\frac{1}{3}\times 15$

Step III: Then simplify it :-

=$\frac{15}{5}:\frac{15}{3}$

= 3: 5
