Question

Select the correct combination of mathematical signs to replace ∗ signs and to balance the given equation.

20 ∗ 3 ∗ 4 ∗ 8

• A. =, +, ×
• B. +, ×, =
• C. =, ×, +
• D. ×, =, +

Answer 1

Answer:

C. =, ×, +

Let us check out,

1) $20 = 3 + 4\times{8}, False$

20 = 3 + 32

20 ≠ 35 

2) $20 + 3\times{4} = 8, False$

20 + 12 = 8

32 ≠ 8

3) $20 = 3\times{4} + 8, True$

20 = 12 + 8

20 = 20

4) $20\times{3} = 4 + 8, False$

60 = 4 + 8

60 ≠ 12

Hence, ‘=, ×, +’ is the correct sequence.
