Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
150*3*10*2*7*46

Correct option is A

Given: 150 * 3 * 10 * 2 * 7 * 46

We need to replace * with mathematical symbols to make the equation balanced. Let's go through each option.

Option A: ÷, +, -, ×, =

Expression:

150 ÷ 3 + 10 - 2 × 7 = 46

1.      Divide: 50 + 10 - 2 × 7 = 46

2.      Multiplication: 50 + 10 - 14 = 46

3.      Addition: 60 - 14 = 46

4.      Subtract: 46 = 46

This equation is correct.

Option B: -, ×, +, ÷, =

Expression:

150 - 3 × 10 + 2 ÷ 7 = 46

1.      Divide: 150 - 3 × 10 + 0.2857 = 46

2.      Multiplication: 150 - 30 + 0.2857 = 46

3.      Addition: 150.2857 -30 = 46

4.      Subtract: 120.2857 ≠ 46

Option C: +, -, ÷, ×, =

Expression:

150 + 3 - 10 ÷ 2 × 7 = 46

Simplify step by step:

1.      Divide: 150 + 3 - 5 × 7 = 46

2.      Multiplication: 150 + 3 - 35 = 46

3.      Addition: 153 - 35 = 46

4.      Subtract: 118 ≠ 46

Option D: ×, +, ÷, -, =

Expression:

150 × 3 + 10 ÷ 2 - 7 = 46

Simplify step by step:

1.      Divide: 150 × 3 + 5 - 7 = 46

2.      Multiplication: 450 + 5 - 7 = 46

3.      Addition: 455 - 7 = 46

4.      Subtract:448 ≠ 46

Correct Option A.
