Answer 1

help

Answer 2

Okay you're going to have to help me with this one too :P how many inches in a foot? (I'm metric lol)

Answer 3

12 inches in a foot

Answer 4

Okay so 15 feet = 75 inches. So now what we have to do is compare what is on the page to the height in real life. A scale is usually a ratio between the two, so what is the ratio between 75 inches and the inches on the page?

Answer 5

idk how to do ratio

Answer 6

Okay so usually you just divide one by the other (so the real life amount over the page amount).

Answer 7

so divide 15/75

Answer 8

(sorry had to rescue my clothes off the washline :P) no, its 75inches/5inches (you have to have them in the same units).

Answer 9

ow lol k

Answer 10

:D

Answer 11

Hmm so 75/5 = 15, so that means for every 1 inch on the paper, it is 15 inches in real life. So that's why we have the 1:15, however this isn't in any of the options (did you write it wrong?) or have I got something wrong (I may have..I'm a little rusty!)

Answer 12

um idk
