• A. 57
• B. 44
• C. 69
• D. 61

Answer 1

Answer:

A. 57

Let’s simplify step by step:

$[(12 \div 4)\times[\frac{15}{5}+ \frac{16}{1}\times(9-8)]]$
Solve brackets

$12 \div 4 = 3$
$9 - 8 = 1$
Substitute values

$3 \times \left[\frac{15}{5} + \frac{16}{1} \times 1 \right]$
Simplify fractions

$\frac{15}{5} = 3,\quad \frac{16}{1} = 16$
So expression becomes:
$3 \times (3 + 16 \times 1)$
Multiply first

$16 \times 1 = 16$
$3 + 16 = 19$
Final multiplication

$3 \times 19 = 57$
Final Answer:

$\boxed{57}$
