Answer 13

okay so what you want to do is make it so that the two fractions have the same denominator

Answer 14

so what you can do is make 1/2 into 5/10

Answer 15

so the container is 8/10 full, or 80% full

Answer 16

I made it 5/10 how can i tell how many gallons

im working it hang on

Answer 19

If x is tank volume in gallons

\[\frac{3}{10}x+5=\frac{1}{2}x\]

Answer 20

sry i dont get it

Answer 21

thx though

Answer 22

It went from 3/10 full, to 5/10 full (since 1/2 is 5/10)

Which means they added 2/10 of water.

They also told you that the 2/10 ths they added was 5 gallons. So if x is the total tank size, then\[\large \frac{ 2 }{ 10 } x = 5\]

Are you still stuck?
