Answer 2

find a common denominator for 1/2 and 4/5 and convert the fractions so that they share it.

Answer 3

the common denominator would be one?

Answer 4

It would be ten. The common denominator is the number that is the same on the bottom. Its easiest to find it by multiplying the bottom halves of the fraction together.

Answer 5

so 2/10 and 4/10

Answer 6

Not quite. Since you are multiplying the bottom by five in the first fraction, you have to multiply the top by five too. The first fraction is 5/10
Based on that can you find the second

Answer 7

so 10/10=1

Answer 9

Yes.

Answer 10

4/5 turns into 8/10

Answer 11

so the container holds 8/10 gallons

Answer 12

Yes. You then subtract the amount it holds now from the amount it started with

Answer 13

3?

Answer 14

Yes. It was filled an additional 3/t0 of the way

Answer 15

that wasn't correct it said

Answer 16

Since nine additional gallons were added in, you can divide nine by three to see how many gallons are in each tenth

Answer 17

it'll still be 3

Answer 18

wouldnt it?

Answer 19

Yeah. 1/10 is three gallons. You then have to multiply that by ten to get the total amount that the container can be filled

Answer 20

Answer 22

Not quite. If three gallons are 1/10 then 3x 10 will be the total

Answer 23

3x 10?

Answer 24

???

Answer 25

Yes. the tank can hold 30 gallons total since three times ten is thirty which is all ten tenths
