2/5+m=5/6 step by step explanation

13/30

Step-by-step explanation:

Begin by getting 2/5 on the right side.

2/5-2/5 + m = 5/6 - 2/5

The lowest common denominator is 6 * 5 which are prime to each other.

m = 5/6 - 2/5                          Multiply the tops and bottoms to make the bottoms 30

m = 5*5/(6*5) - (2*6)/(5*6)

m = (25 - 12)/30

m = 13/30

use formula for the circle a=3.14
