Which pair of signs, taken in the given order, should fill the two blanks to make the equation correct?
63 ___ 7 ___ 5 = 14
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → ÷ and +
Put the two signs of an option in the blanks in the given order and work out the left side by BODMAS. The option is right only when the left side equals 14.
With ÷ and + the left side reads 63 ÷ 7 + 5
\(63\div7=9\)
\(9+5=14\), which equals the right side
Why the other options are incorrect
Option (1) ÷ and × — Incorrect. 63 ÷ 7 × 5 \(=\) 45, not 14.
Option (2) – and × — Incorrect. 63 – 7 × 5 \(=\) 28, not 14.
Option (3) ÷ and – — Incorrect. 63 ÷ 7 – 5 \(=\) 4, not 14.
