Answer 1

EXPLANATION :

From the problem, we have the fraction :

`(30)/(80)`

We need to find the common factor between the numerator and the denominator.

30 = 2 x 3 x 5

80 = 2 x 2 x 2 x 2 x 5

The common factor is 2 x 5 which is equal to 10.

Divide both numerator and denominator by 10 :

`(30/10)/(80/10)=(3)/(8)`

ANSWER :

The answer is B. 3/8
