Question

$\frac{1}{2}$, $\frac{2}{3}$, $\frac{3}{4}$ and $\frac{4}{5}$ as like fractions are $\frac{40}{60}$, $\frac{30}{60}$, $\frac{45}{60}$ and $\frac{48}{60}$ repectively.

• A. True
• B. False

Answer 1

The correct option is B

False

L.C.M. of the denominators of the given fractions is 60.

So, inorder to make the denominators of $\frac{1}{2}$, $\frac{2}{3}$, $\frac{3}{4}$ and $\frac{4}{5}$ same, we multiply the numerator and the denominator of $\frac{1}{2}$ by 30, numerator and the denominator of $\frac{2}{3}$ by 20, numerator and the denominator of $\frac{3}{4}$ by 15 and numerator and the denominator of $\frac{4}{5}$ by 12.

That is, $\frac{1\times 30}{2\times 30}$ = $\frac{30}{60}$, $\frac{2\times 20}{3\times 20}$ = $\frac{40}{60}$, $\frac{3\times 15}{4\times 15}$ = $\frac{45}{60}$ and $\frac{4\times 12}{5\times 12}$ = $\frac{48}{60}$

Therefore, $\frac{1}{2}$, $\frac{2}{3}$, $\frac{3}{4}$ and $\frac{4}{5}$ as like fractions are $\frac{30}{60}$, $\frac{40}{60}$, $\frac{45}{60}$ and $\frac{48}{60}$.
