Question

Express - 5 over 8 as a rational number with numerator 15​

Answer 1

In this question we will use the concept of equivalent fractions

1) let the denominator be 'x' and we know that the numerator is 15

5/8 =15/x

x=15×8/5

x = 24

2) again take denominator as x and the numerator is -10

5/8 = -10/x

x = -10×8÷5

x = -16
