Question

Evaluate each of the following:

$\frac{13}{15} - \frac{12}{25}$

Open in App

Solution

To find: $\frac{13}{15} - \frac{12}{25}$

$∴ \frac{13}{15} - \frac{12}{25} = \frac{13 \times 5}{15 \times 5} - \frac{12 \times 3}{25 \times 3}$

$= \frac{65}{75} - \frac{36}{75}$
$= \frac{65 - 36}{75}$
$= \frac{29}{75}$

Thus, $\frac{13}{15} - \frac{12}{25} = \frac{29}{75}$

Evaluate each of the following:

$\frac{13}{15} - \frac{12}{25}$

To find: $\frac{13}{15} - \frac{12}{25}$

$∴ \frac{13}{15} - \frac{12}{25} = \frac{13 \times 5}{15 \times 5} - \frac{12 \times 3}{25 \times 3}$

$= \frac{65}{75} - \frac{36}{75}$
$= \frac{65 - 36}{75}$
$= \frac{29}{75}$

Thus, $\frac{13}{15} - \frac{12}{25} = \frac{29}{75}$
