Answer 1

Answer:

2) 10

Step-by-step explanation:

Let the numerator be x.

According to Question,

(x+2) / 15 = 4/5

=> x+2 = 4×3

=> x+2 = 12

=> x = 12-2

=> x = 10

Hence, the numerator is 10.

Answer 2

Answer:

10

Step-by-step explanation:

Let the fraction be a/15 , where a is the numerator

a+2/15 = 4/5

Thus,

a+2/15=12/15

a+2=12

a=12-2

a=10
