1 1/2x2/3=22/6 or you can divide it 11/2 divided by 2/3 =3/4

Answer:

1 1/9 inches

Explanation:

The scale of the drawing is the ratio of the drawing size to the actual size. It applies to all drawing dimensions. This lets us write a proportion for the width of the drawing.

__

setup

drawing size / actual size = (1 in)/(1 1/2 in) = (width)/(1 2/3 in)

solution

Multiplying by 1 2/3 in, we find the width to be ...

width = (1 2/3 in) × (1 in)/(1 1/2 in)

width = (5/3 in)×1/(3/2) = (5/3 in)(2/3) = 10/9 in = 1 1/9 in

The width of the drawing is 1 1/9 inches.
