Question

Find answers to the following. Write and indicate how you solved them.

Is ${\displaystyle \frac{5}{9}}$ equal to ${\displaystyle \frac{4}{5}}$?

Answer 1

${\displaystyle \frac{5}{9},\frac{4}{5}}$

Converting these into like fractions,

${\displaystyle \frac{5}{9}=\frac{5}{9}\times \frac{5}{5}=\frac{25}{45}}$

${\displaystyle \frac{4}{5}=\frac{4}{5}\times \frac{9}{9}=\frac{36}{45}}$

As, ${\displaystyle \frac{36}{45}\ne \frac{25}{45}}$,

Therefore, ${\displaystyle \frac{5}{9} \text{is not equal to} \frac{4}{5}}$.
