After interchanging which two signs, the value of the given equation will be '1'?
12 x 6 - 28 + 3 ÷ 9
Answer & explanation
Correct answer: option 3
In the equation, 12 x 6 - 28 + 3 ÷ 9
if we interchange ÷ and x,
it becomes 12 ÷ 6 - 28 + 3 x 9
Using BODMAS rule,
= 12 ÷ 6 - 28 + 3 x 9
= 2 - 28 + 27
= 1
