Ratio = 1 : 4
Step-by-step explanation:
Total marbles = 10
Given 1/5 is red, that is 1/5 of the total marbles are red
![\frac{1}{5} \ of \ 10 = \frac{1}{5} \times 10 = 2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%5C%20of%20%5C%2010%20%3D%20%5Cfrac%7B1%7D%7B5%7D%20%5Ctimes%2010%20%3D%202)
Therefore , 10 - 2 = 8 marbles are blue.
Ratio of red marbles to blue marbles
