Fill in operators — Choose the correct sequence of signs to make the statement true: 40 * 2 * 4 * 3 * 8

Verbal Reasoning Mathematical Operations Difficulty: Medium
Choose an option
  • A
    + - ÷ =
  • B
    ÷ + = x
  • C
    + ÷ x =
  • D
    + x - =

Answer

Correct Answer: ÷ + = x

Explanation

Introduction / Context:We must pick a sequence of operations so that the expression becomes a true equation. The four symbols fill in order and one of them must be “=” to split left and right sides.

Given Data / Assumptions:

  • Template: 40 {s1} 2 {s2} 4 {s3} 3 {s4} 8
  • Standard precedence applies on each side of the “=”.

Concept / Approach:Try choices that place “=” as the third symbol so the last symbol lands on the right-hand side. Option B yields a clean check.

Step-by-Step Solution:

Option B: s1=÷, s2=+, s3==, s4=× → 40 ÷ 2 + 4 = 3 × 8.Left: 40 ÷ 2 + 4 = 20 + 4 = 24.Right: 3 × 8 = 24.Equality holds → Option B is correct.

Verification / Alternative check:Test other options quickly; they fail to balance to a single equality.

Why Other Options Are Wrong:

  • They either misplace “=” or produce unequal numeric results.

Common Pitfalls:

  • Ignoring precedence and evaluating strictly left-to-right across the equality.

Final Answer:÷ + = x
