Question

Out of the following fractions which is the smallest and which is the greatest?
$\frac{1}{2},\frac{6}{3},\frac{3}{5},\frac{3}{2},\frac{3}{4}$

Answer 1

$\text{Converting the fraction}\frac{6}{3}\text{into its}\text{simplest form.}$
$\frac{6}{3}=2=\frac{2}{1}$

$\therefore \text{LCM for the fractions}\frac{1}{2},\frac{2}{1},\frac{3}{5},\frac{3}{2},\frac{3}{4}\text{is 20.}$
Multiplying the lcm in numerator and denominator,
$⟹\frac{1}{2}=\frac{10}{20}$

$⟹\frac{2}{1}=\frac{40}{20}$

$⟹\frac{3}{5}=\frac{12}{20}$

$⟹\frac{3}{2}=\frac{30}{20}$

$⟹\frac{3}{4}=\frac{15}{20}$

Now that the denominator is equal, we can compare the fractions. The numerator 40 is the greatest and 10 is the least. Hence, the corresponding original fractions will be the greatest and the least.
$\therefore$ Greatest fraction = $\frac{6}{3}$ = 2 and the smallest fraction = $\frac{1}{2}$
