Question

Jamal is making a scale drawing of his favorite painting. He uses the scale 1/3 inch:4 inches. If the width of his drawing is 6 inches, what is the width of the painting?-8-25-30-72

Answer 1

We can express the scale 1/3:4 with the ratio:

`(4)/((1)/(3))`

We can simplify this ratio like this:

`(4)/((1)/(3))=(4*3)/(1)=12`

And if we want to scale the width of the drawing from 6 inches, we just have to multiply 6 by the ratio, like this:

`12*6=72`

Then, the width of the painting is 72
