Answer:

#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#
