Question

A letter 8.5 inches by 11 inches is reduced to n inches by 8.25 inches. Find n.

Answer 1

n = 6.375

Explanation:

To find n, you have to create a proportion:

`(8.5)/(11)` =
`(n)/(8.25)`

Now, cross-multiply:

11n = 70.125

Finally, divide both sides by 11 to find n:

`(11n)/(11)` =
`(70.125)/(11)`

n = 6.375
