1:3.75=4:15

Explanation:

Ratio is generally with whole numbers, but here we have one number as 3.75, which is a mixed fraction in which we have 0.75 as fractional part.

In ratios if we multiply by a common number, it remains same. Hence, let us multiply by a number which makes it whole.

It is apparent that if we multiply 0.75 by 4, it becomes whole.

Hence 1:3.75

= 1×4:3.75×4

= 4:(12+0.75×4)

= 4:(12+3)

= 4:15
