Question

Convert the following unlike fractions to like fractions:\n
$\frac{1}{5},\frac{3}{10}$

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

$\frac{1}{5},\frac{3}{10}$
Like fractions are fractions that have the same denominator.
LCM of 5 and 10 is 10 (since 10 is a multiple of 5, 10 becomes their LCM)
Multiplying both numerator and denominator of $\frac{1}{5}$ by 2 we get
$\frac{1}{5}=\frac{(1\times 2)}{(5\times 2)}=\frac{2}{10}$
Like fractions are $\frac{2}{10}$ and $\frac{3}{10}$
