Question

63:90 in its simplest form

Answer 1

Divide each side by a common factor to simplify. 9 is a common factor of both 63 and 90.

63/9=7 and 90/9=10.
So 63:90 can also be written as 7:10.

Therefore, the answer is 7:10.

Answer 2

Divide both by 3
63/3= 21
90/3= 30

21/30
We can simplify it less

21/3=7
30/3=10

The final answer is 7/10
