Question

Select those rational numbers which can be written as a rational number with numerator 6:

$\frac{1}{22},\frac{2}{3},\frac{3}{4},\frac{4}{-5},\frac{5}{6},\frac{-6}{7},\frac{-7}{8}$

Answer 1

Given rational numbers that can be written as a rational number with numerator 6 are:

$$\begin{gathered} \frac{1}{22}(\mathrm{On}\mathrm{multiplying}\mathrm{by}6)=\frac{6}{132} \\ \frac{2}{3}(\mathrm{On}\mathrm{multiplying}\mathrm{by}3)=\frac{6}{9} \\ \frac{3}{4}(\mathrm{On}\mathrm{multiplying}\mathrm{by}2)=\frac{6}{8} \\ \frac{-6}{7}(\mathrm{On}\mathrm{multiplying}\mathrm{by}-1)=\frac{6}{-7} \end{gathered}$$
