Answer:

5[tex]\frac{1}{2}[/tex]

Explanation:

1. Find a common denominator for the three fractions. A common denominator is a number all three numbers divide into evenly. The lowest common denominator for 4, 3, and 6 is 12.

2. Find the numerators. This can be done by multiplying the current numerators by however many times the old denominator goes into the new denominator.

4 goes into 12 3 times

3 goes into 12 4 times

6 goes into 12 2 times

1 x 3 = 3

2 x 4 = 8

1 x 6 = 6

So, the fractions become:

[tex]1\frac{3}{12} + 2\frac{8}{12} + 1\frac{2}{12}[/tex]

3. Add the numerators of the new fractions and keep the denominator the same.

[tex]4 \frac{13}{12}[/tex]

4. Convert the improper fraction to a mixed number.

[tex]1 \frac{1}{12}[/tex]

5. Finally, add the whole numbers.

1 + 4 = 5
