Deon's gas tank is (1)/(3)
full. after he buys 2
gallons of gas, it is (1)/(2)
full. how many gallons can deon's tank hold?

let's say it holds "x" gallons of gas.

how much is 1/3 of that?  well is just (1/3)x.

how about 1/2 of that?  well is just (1/2)x.

we know that

notice, we simply multiplied both sides by the LCD of all fractions, to just do away with the denominators.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
