Question

jim and Jon are painting a fence. Jon painted 1/4 of the fence. Jim painted 5/12 of the fence. how much of the fence did they paint in total?

Answer 1

Our first step is the find the lcm of 4 and 12 so we can add the two fractions without having a problem.

The lcm of 4 and 12 is clearly 12 because 12 is a multiple of 4. 12 divided by 4 is 3, so you must multiply by 3/3 to be able to add the two fractions.

1/4*(3/3)=3/12.

So, 3/12+5/12=7/12.

Jim and Jon painted 7/12 of the the fence.

Answer 2

Answer:

2/3 of the fence

Step-by-step explanation:

Jim painted 1/4 of the fence

Jon painted 5/12 of the fence

Together they painted

1/4+5/12 of the fence

We need a common denominator to add the fractions

The common denominator is 12

1/4*3/3 + 5/12

3/12 + 5/12

8/12

This can be simplified by dividing the top and bottom by 4

2/3

Together, they painted 2/3 of the fence.
