Question

How to solve this?

x + 2x/5 + x/10

Answer 1

LCM of 5 and 10 = 1

x/10 will remain same

$\frac{x}{1} = \frac{x \times 10}{1 \times 10} = \frac{10x}{10} \\ \frac{2x}{5} = \frac{2x \times 2}{5 \times 2} = \frac{4x}{10} \\ \frac{x}{10} = \frac{x \times 1}{10 \times 1} = \frac{ x}{10}$

$\frac{10x + 4x + x}{10} = \frac{15x}{10} = \frac{3x}{2}$
