Select the correct combination of mathematical signs to sequentially replace the % signs and to balance the given equation.
[{(32 % 28) % (6 % 4)} % (1 % 7)] % 5 % 20
Answer & explanation
Correct answer: option 1
[{(32 % 28) % (6 % 4)} % (1 % 7)] % 5 % 20
Applying option 1 −, +, ×, ÷, ×, ×, =
[{(32 − 28) + (6 × 4)} ÷ (1 × 7)] × 5 = 20
[{(32 − 28) + (6 × 4)} ÷ (1 × 7)] × 5 = 20
[{4 + 24} ÷ (1 × 7)] × 5 = 20
[ 28 ÷ 7] × 5
4 × 5
20 = 20
