By interchanging which two numbers the equation will be correct?
9 x 3 ÷ 6 + 4 - 8 = 1
Answer & explanation
Correct answer: option 3
In the equation, 9 x 3 ÷ 6 + 4 - 8 = 1
if we interchange 3 and 4, it becomes:
9 x 4 ÷ 6 + 3 - 8 = 1
Using BODMAS rule,
LHS = 9 x 4 ÷ 6 + 3 - 8
= 9 x 4 ÷ 6 + 3 - 8
= 6 + 3 - 8
= 1 = RHS
Thus, the equation becomes correct with this interchange.
