Which of the following combination of signs would make the given equation correct?

(50 × 5) + 4 ÷ 16 = 56

Answer: B

The combination is ÷, ×, +.

Replace the three signs in order:

\[ \begin{aligned} (50 \div 5) \times 4 + 16 &= 10 \times 4 + 16 \\ &= 56 \end{aligned} \]

The other combinations give \((50 + 5) \div 4 \times 16 = 220\), \((50 + 5) \times 4 \div 16 = 13.75\) and \((50 \times 5) \div 4 + 16 = 78.5\).
