You want to produce a scale drawing of your living room, which is 24 ft by 15 ft. If you use a scale of 4 in=6 ft, what will be the dimensions of your scale drawing.

I think the dimensions are 16 ft by 10 ft. Is this right?

No. Can you explain what you did to get that?

I tried to make a proportion 4/6=x/24 and that's how I got 16. Then I got another proprtion 4/6=x/15 and I got 10. What did I do wrong?

If you just think about how realistic your answer is, a drawing of those dimensions would be much too difficult to handle. That's a good way to know you've done something wrong.

Start by finding the scale for 1 foot. That should put you in the right direction.

Does 1 ft equals 1.5 in?

To get the conversion factor for every foot, convert feet to inches.

4 in = 6 ft

4 in = 72 in

(divide by 4)

1 in = 18 in

For every 18 inches (1.5 ft), your scale will be only 1 inch. You must have done this backwards.

Try your multiplication again to get the final answer.
