Question

If 42 × 43 = n, then which division equation is also true?

Answer 1

43 divided by n is equal to 42

Answer 2

The division equations
`43=n/ 42` and
`42=n/ 43` are true.

Explanation:

The given multiplication equation is

`42* 43=n`

We need to find a division equation which is true if 42 × 43 = n.

Case 1: Divide both sides by 42.

`(42* 43)/(42)=(n)/(42)`

`43=n/ 42`

Case 2: Divide both sides by 43.

`(42* 43)/(43)=(n)/(43)`

`42=n/ 43`

Therefore the division equations
`43=n/ 42` and
`42=n/ 43` are true.
