Question

If $1m=100cm$, then $\frac{3}{4}m=$____.

• A. $10cm$
• B. $25cm$
• C. $50cm$
• D. $75cm$

Answer 1

The correct option is D $75cm$

Given: $1m=100cm$
$\frac{3}{4}m$ is nothing but one half and one quarter metre.

Quarter is half of half.
Half of $100cm$ is $50cm$, half of $50cm$ is $25cm$.
The half of half which is quarter of $100m$ is $25cm$.

Now, $\frac{3}{4}cm=$ Half metre + Quarter metre
$=50cm+25cm=75cm$
