Question

Which of the following interchanges of signs would make the given equation correct? 15 - 54 × 18 + 16 ÷ 2 = 44

• A. - and +
• B. + and x
• C. ÷ and x
• D. - and ÷

Answer 1

Answer:

C. ÷ and x

Interchanging ( $- \leftrightarrow \times ) and ( + \leftrightarrow \div )$

Result becomes:
$15 \div 54 - 18 + 16 \times 2$

$(16 \times 2 = 32)$

$15/54 - 18 + 32 \approx 0.278 + 14 = 44.278 \approx 44$

Final Answer:

Swap − with × and + with ÷.
