Answer:
The answer is 5/12
To solve this, we first have to find a common denominator between the three fractions.
To find a common denominator, which is a multiple that all of the bottom parts of the fractions share, we just have to start guessing.
What is a multiple 4, 3, and 2 all share?
Well, 3 and 2 both share the multiple 6, but 4 doesn't.
What about 12?
4 x 3 = 12
3 x 4 = 12
2 x 6 = 12
All of the numbers share the common denominator of 12
So, we have to multiply all the top numbers now.
5 x 3 = 15
1 x 4 = 4
1 x 6 = 6
So here are our 3 new fractions:
15/12 - 4/12 - 6/12
Now this is a lot easier to solve
15/12 - 4/12
15 - 4 = 11
11/12
11/12 - 6/12
11 - 6 = 5
5/12
The answer is 5/12
