Which two signs need to be interchanged to make the given equation correct?
3÷2−4×5+5=1
- A+ and −
- B× and −
- C÷ and ×
- D+ and ÷
Solution & Step-by-step Explanation
Let's check Option D by interchanging + and ÷:
The original equation is: 3÷2−4×5+5=1
After replacing ÷ with + and + with ÷:
3+2−4×5÷5
Applying BODMAS rule:
Division: 5÷5=1
3+2−4×1
Multiplication: 4×1=4
3+2−4
Addition and Subtraction:
5−4=1
Since LHS=RHS=1, Option D is correct.
