Question

Select the correct combination of the mathematical signs that can be filled to balance the following equation:

12__4__2__2__5__3

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

Answer 1

Answer:

B. ÷, ×, +, =, +

Solution: 1) +, =, ÷, ×, + Given expression is 12__4__2__2__5__3 Replacing __ with mathematical signs and applying BODMAS rule, we get : 12 + 4 = 2 ÷ 2 × 5 + 3 L.H.S = 12 + 4 = 16 R.H.S = 2 ÷ 2 × 5 + 3 = 1 × 5 + 3 = 5 + 3 = 8 L.H.S ≠ R.H.S 2) ÷, ×, +, =, + Given expression is 12__4__2__2__5__3 Replacing __ with mathematical signs and applying BODMAS rule, we get : 12 ÷ 4 × 2 + 2 = 5 + 3 L.H.S = 12 ÷ 4 × 2 + 2 = 3 × 2 + 2 = 6 + 2 = 8 R.H.S = 5 + 3 = 8 L.H.S = R.H.S 3) ÷, ×, -, =, × Given expression is 12__4__2__2__5__3 Replacing __ with mathematical signs and applying BODMAS rule, we get : 12 ÷ 4 × 2 - 2 = 5 × 3 L.H.S = 12 ÷ 4 × 2 - 2 = 3 × 2 - 2 = 6 - 2 = 4 R.H.S = 5 × 3 = 15 L.H.S ≠ R.H.S 4) ÷, ×, =, +, + Given expression is 12__4__2__2__5__3 Replacing __ with mathematical signs and applying BODMAS rule, we get : 12 ÷ 4 × 2 = 2 + 5 + 3 L.H.S = 12 ÷ 4 × 2 = 3 × 2 = 6 R.H.S = 2 + 5 + 3 = 10 L.H.S ≠ R.H.S Hence, ÷, ×, +, =, + is the correct answer.
