Question
Find the sum:
$\frac{5}{8}+\frac{3}{10}$
$\frac{5}{8}+\frac{3}{10}$
✓
Answer
We have,
$\frac{5}{8}+\frac{3}{10}$
Taking the LCM of 8 and 10, we get
2 × 4 × 5 = 40
Now, we convert the given fractions to equivalent fractions by making the denominators 40,
$=\frac{5\times5}{8\times5}+\frac{3\times4}{10\times4}$
$=\frac{25}{40}+\frac{12}{40}$
$=\frac{25+12}{40}$
$=\frac{37}{40}$
$\frac{5}{8}+\frac{3}{10}$
Taking the LCM of 8 and 10, we get
2 × 4 × 5 = 40
Now, we convert the given fractions to equivalent fractions by making the denominators 40,
$=\frac{5\times5}{8\times5}+\frac{3\times4}{10\times4}$
$=\frac{25}{40}+\frac{12}{40}$
$=\frac{25+12}{40}$
$=\frac{37}{40}$
