Michael mixes 60 ounces of red paint with 15 ounces of blue paint to get a shade of
purple. what is the ratio of red paint to blue paint expressed in lowest terms

4:1

Step-by-step explanation:

basically you'd need to divide 60 by 15 since 15 is their common multiple.

"60/15= 4"

and you cant forget to divide 15 by the same number.

"15/15=1"

whichever comes first in the problem comes first in the ratio.

"Michael mixes 60 ounces of red paint" 60 simplified is 4 so we put 4 first.

"15 ounces of blue paint" 15 simplified is 1. so we put 1 last.

in the end we get the ratio '4:1'

if x = 1, then the answer is 3.5
