Question

JJ's current living room is 15 ft x 22 ft. In his scale drawing, 1 in = 1 ft, so the dimensions of his drawing are 15 in x 22 in.

What will the dimensions of the new scale drawing be if he multiplied by a scale factor of 2/3?

Answer 1

330

Explanation:

Answer 2

Current Dimensions: 15 in x 22 in

Scale Factor:

2 /3

Start with the 15 inch side.

2 /3 (15 in) = Multiply the dimension by the scale factor.

2 /3 ( 15/1 in)= Rewrite the whole number as a fraction.

30 /3 in = 10 in Multiply and simplify.

Now scale down the 22 in side.

2 /3(22 in) = Multiply the dimension by the scale factor.

2 /3(22/1 in) Rewrite the whole number as a fraction.

44 /3 in=14 2/3 in Multiply and simplify.

The new drawing will be 10 in x 14 2/4

The new scale drawing is smaller than the original drawing, since JJ multiplied by a number smaller than 1.
