\( \Large 81 \div 36\ of\ \frac{1}{4}+\frac{2}{5} \times 3\frac{3}{4} = ? \)

A) \( \Large \frac{21}{2} \)
B) \( \Large \frac{21}{4} \)
C) \( \Large \frac{21}{7} \)
D) 6

Correct Answer:

A) \( \Large \frac{21}{2} \)

Description for Correct answer:
\( \Large 81 \div 36\ of\ \frac{1}{4}+\frac{2}{5} \times 3\frac{3}{4} \)

=\( \Large 81 \div 9+\frac{2}{5} \times \frac{15}{4}=81 \div 9+\frac{3}{2} \)

=\(9+\frac{3}{2}=\frac{21}{2} \Large \)
