Question

Convert the following unlike fractions into like fractions $\frac{5}{14},\frac{1}{2},\frac{3}{7},\frac{7}{8}$

Answer 1

$\frac{5}{14},\frac{1}{2},\frac{3}{7},\frac{7}{8}$

Take the LCM of the denominators i.e. 56

$$\begin{gathered} \frac{5}{14}=\frac{5\times 4}{14\times 4}=\frac{20}{56} \\ \frac{1}{2}=\frac{1\times 28}{2\times 28}=\frac{28}{56} \\ \frac{3}{7}=\frac{3\times 8}{7\times 8}=\frac{24}{56} \\ \frac{7}{8}=\frac{7\times 7}{8\times 7}=\frac{49}{56} \end{gathered}$$

Therefore, $\frac{20}{56},\frac{28}{56},\frac{24}{56},\frac{49}{56}$are the like fractions.
