MCQ
The product of $7$ and $6\frac{3}{4}$ is:
- A$42\frac{1}{4}$
- ✓$47\frac{1}{4}$
- C$42\frac{3}{4}$
- D$47\frac{3}{4}$
✓
Answer
Correct option: B.
$47\frac{1}{4}$
Given, $7\times6\frac{3}{4}$
$\because\ 6\frac{3}{4}=\frac{(6\times4+3)}{4}=\frac{24+3}{4}=\frac{27}{4}$
$\therefore7\times6\frac{3}{4}=7\times\frac{27}{4}=\frac{189}{4}=47\frac{1}{4}$
Hence, the product of $7$ and $6\frac{3}{4}\ \text{is}\ 47\frac{1}{4}$
