Question

A photograph measures 10 in. wide by 18 in. long. The picture is reduced so that the length is 6 in.

What is the new width?

Answer 1

Data:
Wide by Length
10 by 18
y by 6

Solving: Rule of three (directly proportional)

`(10)/(18) = (x)/(6)`
multiply cross

`18*x = 10*6`

`18x = 60`

`x = (60)/(18) \to\:\boxed{x\approx3.3\:in}`

Answer:
the new width is aproximately 3.3 in
