Answer 2

Adding Fractions

To solve the addition of fractions, we'll follow these steps:

1. Convert mixed numbers to improper fractions. 2. Find a common denominator for each pair of fractions. 3. Add the fractions together.

Let's solve each of the given addition problems step by step.

1) Adding 5 6/8 and 4 15/12

First, we convert the mixed numbers to improper fractions: - 5 6/8 = 5 + 6/8 = 5 + 3/4 = 20/4 + 3/4 = 23/4 - 4 15/12 = 4 + 15/12 = 4 + 5/4 = 16/4 + 5/4 = 21/4

Now, we add the improper fractions: - 23/4 + 21/4 = 44/4 = 11

The sum of 5 6/8 and 4 15/12 is 11.

2) Adding 24/35, 5/21, and 4/7

To add these fractions, we need to find a common denominator. The least common multiple of 35, 21, and 7 is 105.

Now, we convert each fraction to have a denominator of 105: - 24/35 = 72/105 - 5/21 = 25/105 - 4/7 = 60/105

Adding the fractions together: - 72/105 + 25/105 + 60/105 = 157/105 = 1 52/105

The sum of 24/35, 5/21, and 4/7 is 1 52/105.

3) Adding 13/100, 7/60, and 29/150

We find a common denominator for 100, 60, and 150, which is 300.

Converting each fraction to have a denominator of 300: - 13/100 = 39/300 - 7/60 = 35/300 - 29/150 = 58/300

Adding the fractions together: - 39/300 + 35/300 + 58/300 = 132/300 = 11/25

The sum of 13/100, 7/60, and 29/150 is 11/25.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
