For answering ratios in the decimal form we need to learn the basic inverse values of all digits from 1 to 10.

For comparing the ratios we can make the ratio into division form

Now here we need the inverse value of 5 and 10.

Inverse value of 5 = 1/5 = 0.2

Inverse value of 10 = 1/10 = 0.1

First ratio 7:10 = 7/10

= 7 * (1/10)

= 7 * (0.1)

= 0.7 _________________(1)

Second ratio 3:5 = 3/5

= 3 * (1/5)

= 3 * (0.2)

= 0.6 ________________(2)

Therefore (1) > (2)

7:10 is greater than 3:5.
