Answer 1

since we know that the scale is really 1cm=10ft, then we can convert the cm to ft.

Answer 2

proportions is my #1 strategy.
\[\frac{ cm }{ ft }=>\frac{ 1 }{ 10 }=\frac{ 5.7 }{ x }\]

Answer 3

Now you can solve for x. Do you know how?

Answer 6

Okay. Good thing you told because i can help you. :)

Answer 7

First. Start off with cross multiplying (not for comparing fractions though, if you understand).

(sorry for the bad handwriting)

So you multiply 10 x 5.7 = 57 (you move the decimal one place to the right since your are multiplying).

Now we have only 57=1x and we want to solve for x. So we have to divide 1 with 1 (to get x by itself) and whatever we do on one side, we do it one the other. Meaning we also divide 57 by 1 = 57.

Your answer should be 57ft (because x=57).
