Question

Find the value of

$[(21 \div 7)\times[\frac{63}{9}+\frac{14}{2}\times(4-2)]]$

• A. 48
• B. 63
• C. 65
• D. 73

Answer 1

Answer:

B. 63

Let’s solve step by step:

$[(21 \div 7)\times[\frac{63}{9}+\frac{14}{2}\times(4-2)]]$
Simplify each part

• $(21 \div 7 = 3)$

• $(\frac{63}{9} = 7)$

• $(\frac{14}{2} = 7)$

• $(4 - 2 = 2)$

  Substitute values

$= 3 \times [7 + 7 \times 2]$
Multiply inside bracket

$7 \times 2 = 14$
$= 3 \times (7 + 14)$
Add

7 + 14 = 21
Final multiplication

$3 \times 21 = 63$
Final Answer:

$\boxed{63}$
