Correct Answer - Option 3 : ÷ and ×
Given equation : 12 ÷ 6 + 24 × 3 - 8 = 72
By going with the options, we check the values
option 1) × and -
12 ÷ 6 + 24 - 3 × 8
= 2 + 24 - 3 × 8
= 2 + 24 - 24
= 2
option 2) - and +
12 ÷ 6 - 24 × 3 + 8
= 2 - 24 × 3 + 8
= 2 - 72 + 8
= - 62
option 3) ÷ and ×
12 × 6 + 24 ÷ 3 - 8
= 12 × 6 + 8 - 8
= 72 + 8 - 8
= 72
option 4) + and ÷
12 + 6 ÷ 24 × 3 - 8
= 12 + 0.25 × 3 - 8
= 12 + 0.75 - 8
= 4.75
Hence, the answer is ÷ and ×
