Question

Johnny measured an apartment and made a scale drawing. He used the scale 9 centimeters = 1 meter. What is the scale factor of the drawing?

Simplify your answer and write it as a ratio, using a colon.

Answer 1

we are given

9 centimeters = 1 meter

we know that

`1m=100cm`

or

`100cm=1m`

now, we can divide both sides by 100

`1cm=(1)/(100) m`

for 9cm

we get

`9*1cm=9*(1)/(100) m`

`9cm=(9)/(100) m`

so, the scale factor is

`=(9)/(100)`..............Answer
