Question

MCC.7.G.1} A gymnasium is 168 feet long and 96 feet wide. On a blueprint, the gymnasium is 8 inches long. What is the width of the gymnasium on the blueprint?

Answer 1

step 1

Find out the scale

Divide the length in the blueprint by the length in the actual

so

8 in/168 ft

step 2

Multiply the actual wide by the scale to obtain the width in the blueprint

`96\cdot(8)/(168)=(768)/(168)=(672)/(168)+(96)/(168)=4+(12)/(21)=4+(4)/(7)=4(4)/(7)in`

answer is option A
