Question 76 (i)

Write the next three rational numbers to complete the pattern:

$\frac{4}{-5},\frac{8}{-10},\frac{12}{-15},\frac{16}{-20},$ __ ___ ___

Answer 1

Given rational number is $\frac{4}{-5}$
So the next three equivalent rational numbers are
$\frac{4\times 5}{-5\times 5}=\frac{20}{-25},\frac{4\times 6}{-5\times 6}=\frac{24}{-30}$ and $\frac{4\times 7}{-5\times 7}=\frac{28}{-35}$
Hence, the next equivalent numbers are $\frac{20}{-25},\frac{24}{-30},\frac{28}{-35}.$
