Question

Subtract $\frac{2}{18}$ from $\frac{8}{18}$ and choose the correct answer.

• A. $\frac{1}{4}$
• B. $\frac{1}{2}$
• C. $\frac{1}{3}$
• D. $\frac{2}{3}$

Answer 1

The correct option is C $\frac{1}{3}$

We have to subtract $\frac{2}{18}$ from $\frac{8}{18}$

$\therefore$ We have to find the value of $\frac{8}{18}-\frac{2}{18}$

Concept: When the two fractions are like fractions then only numerators of both fractions are subtracted .

$\therefore \frac{8}{18}-\frac{2}{18}=\frac{8-2}{18}=\frac{6}{18}$

Now we can factorise the numerator and denominator and cancel the common factors.
$\therefore \frac{8}{18}-\frac{2}{18}=\frac{6}{18}$

$=\frac{2\times 3}{2\times 3\times 3}$

$=\frac{1}{3}$
