Answer:
15" by 10"
Step-by-step explanation:
Use a proportion.
10'/5" = 30"/x
10x = 5 * 30
10x = 150
x = 15"
10'/5" = 20'/y
10y = 5 * 20
10y = 100
y = 10"
Answer: 15" by 10"
Yes she does have enough. Here is why:
If you add 1/4 and 1/4, you get 2/8 which is also 1/2.
3/4 is bigger than one half. If you subtract 1/2 from 3/4, you get 1/4.
So she would have 1/4 left.
Absolutely enough to get to her friends house and back. :)
