Hello!

On one side, the length is 6 mm on the small triangle, and on the big one, it's 10. The ratio is 6:10

You can make a proportion

\frac{6}{10} =  \frac{12}{x}

Cross multiply

10 × 12 = 120

Divide by 6 to get x

120 ÷ 6 = 20

\framebox{x = 20 mm}

Elena’s bedroom door is 0.8 m wide. How wide should the door be on the scale drawing, if the ratio is 1 to 50?
arlik [135]

We are given Elena’s bedroom door's width = 0.8 m.

Also the scale drawing is in the ratio of 1 to 50 that is 1/50.

<em>In order to find the width of  scale drawing, we need to multiply original width of the door by 1/50.</em>

If we multiply 0.8 by 1/50, we get

0.8 × 1/50 = 0.8/50 = 0.016 meter.

So, we can say 0.016 meter wide should the door be on the scale drawing, if the ratio is 1 to 50.
