Question

Carl 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?

Answer 1

First you should Simplify

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

`(3)/(6) + (1)/(3) = (5)/(6)`


Solution
1. Find the LCM between 6 and 3 which is 8
2. Times 3 and 6 to both sides of the equation respectively.

`(3 * 3)/(18) + (6 * 1)/(18)`

`(9 + 6)/(18) = (15)/(18)`
3. Simplify the answer by dividing by 3.
