Question

Mary has three lengths of cable, 3/6 yard long, 1/4 yard long, and 1/3 yard long, which two pieces together make a length of 20/24 yard? I

Answer 1

3/6 + 1/3

Explanation:

20/24 can be devided top and bottom by 4 which would equal 5/6, if you add 3/6 + 1/3 also equals 5/6.

Answer 2

`(3)/(6)+(1)/(3)`

Explanation:

To answer this question, we have to sum each pair of cable and see which one results in 20/24.

`(3)/(6)+(1)/(4)=(12+6)/(24)=(18)/(24)=(3)/(4)`

`(3)/(6)+(1)/(3)=(9+6)/(18)=(15)/(18)=(5)/(6)`

`(1)/(4)+(1)/(3)=(3+4)/(12)=(7)/(12)`

Now, if we simply 20/24, we have:

`(20)/(24)=(10)/(12)=(5)/(6)`

As you can see, the answer is the second sum above, because they have the same basic fraction.

Therefore, the answer is

`(3)/(6)+(1)/(3)`
