Question
Find the difference of:
$\frac{21}{25}\text{ and }\frac{18}{20}$
$\frac{21}{25}\text{ and }\frac{18}{20}$
✓
Answer
We have,
$\frac{21}{25}\text{ and }\frac{18}{20}$
Taking out the $LCM$ of $25$ and $20$, we get
$5 \times 5 \times 4 = 100$
Now, we convert the given fractions tp equivalent fractions by making the denominators $100$
$\frac{21\times4}{25\times4}\text{ and }\frac{18\times5}{20\times5}$
The difference between both the fractions are,
$=\frac{90-84}{100}$
$=\frac{6}{100}$
$=\frac{3}{50}$
$\frac{21}{25}\text{ and }\frac{18}{20}$
Taking out the $LCM$ of $25$ and $20$, we get
$5 \times 5 \times 4 = 100$
Now, we convert the given fractions tp equivalent fractions by making the denominators $100$
$\frac{21\times4}{25\times4}\text{ and }\frac{18\times5}{20\times5}$
The difference between both the fractions are,
$=\frac{90-84}{100}$
$=\frac{6}{100}$
$=\frac{3}{50}$
