Answer 1

The correct option is B

$\frac{2}{3}$

Given fraction is $\frac{12}{18}$.

The greatest common factor between 12 and 18 is 6.

Now convert the numerator and denominator in terms of the greatest common factor

$⟹$ 12 = 6 x 2 and 18 = 6 x 3

$⟹$ $\frac{12}{18}$ = $\frac{6\times 2}{6\times 3}$

= $\frac{2}{3}$

So the lowest form of $\frac{12}{18}$ = $\frac{2}{3}$.
