Find: $\frac{1}{2}$ of $4 \frac{2}{9}$

Open in App

Solution

Evaluate the Expression:
The given expression is $\frac{1}{2}$ of $4 \frac{2}{9}$ .
We know that “of” in an expression represents multiplication.
$∴ \frac{1}{2}$ of $4 \frac{2}{9} = \frac{1}{2} \times \frac{38}{9}$
$= \frac{19}{9}$
$= 2 \frac{1}{9}$
Hence, the required answer is $2 \frac{1}{9}$ .
