Answer 1

Answer:

Step-by-step explanation:

In order to obtain the ratio between numbers, we divide by the largest common factor between both.

In this question, the numbers are;

36 : 90

The largest common faction is 18. Dividing both numbers by 18, we have;

36 / 18 : 90 / 18

2 : 5

The ratio is; 2 : 5
