Question

State true or false:

(iii) $\frac{7}{9} = \frac{7 \times 5}{9 \times 5}$

Open in App

Solution

Step: State true or false

$R H S = \frac{7 \times 5}{9 \times 5} = \frac{35}{45} = \frac{7}{5} = L H S$

So, $\frac{7}{9} = \frac{7 \times 5}{9 \times 5}$ .

Hence, the given statement is true.
