$1:3.75=4:15$

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 $1:3.75$

= $1×4:3.75×4$

= $4:(12+0.75×4)$

= $4:(12+3)$

= $4:15$
