Answer 2

1) 2 1/5 + 7 3/4

To add mixed numbers, we first need to convert them into improper fractions.

2 1/5 can be written as (2 * 5 + 1) / 5 = 11/5.

7 3/4 can be written as (7 * 4 + 3) / 4 = 31/4.

Now, we can add the fractions:

11/5 + 31/4 = (11 * 4 + 31 * 5) / (5 * 4) = 44/20 + 155/20 = (44 + 155) / 20 = 199/20.

Therefore, 2 1/5 + 7 3/4 = 199/20.

2) 1 4/9 + 3 2/73

To add mixed numbers, we first need to convert them into improper fractions.

1 4/9 can be written as (1 * 9 + 4) / 9 = 13/9.

3 2/73 can be written as (3 * 73 + 2) / 73 = 221/73.

Now, we can add the fractions:

13/9 + 221/73 = (13 * 73 + 221 * 9) / (9 * 73) = 949/657 + 1999/657 = (949 + 1999) / 657 = 2948/657.

Therefore, 1 4/9 + 3 2/73 = 2948/657.

3) 5 9/10 + 2 4/54

To add mixed numbers, we first need to convert them into improper fractions.

5 9/10 can be written as (5 * 10 + 9) / 10 = 59/10.

2 4/54 can be written as (2 * 54 + 4) / 54 = 112/54.

Now, we can add the fractions:

59/10 + 112/54 = (59 * 54 + 112 * 10) / (10 * 54) = 3186/540 + 1120/540 = (3186 + 1120) / 540 = 4306/540.

Simplifying the fraction, we get:

4306/540 = 2153/270 = 43/5.

Therefore, 5 9/10 + 2 4/54 = 43/5.

4) 6 7/12 + 4 31/48

To add mixed numbers, we first need to convert them into improper fractions.

6 7/12 can be written as (6 * 12 + 7) / 12 = 79/12.

4 31/48 can be written as (4 * 48 + 31) / 48 = 223/48.

Now, we can add the fractions:

79/12 + 223/48 = (79 * 48 + 223 * 12) / (12 * 48) = 3792/576 + 2676/576 = (3792 + 2676) / 576 = 6468/576.

Simplifying the fraction, we get:

6468/576 = 113/8.

Therefore, 6 7/12 + 4 31/48 = 113/8.

5) 2 5/12 + 3 + 1 19/30

To add mixed numbers, we first need to convert them into improper fractions.

2 5/12 can be written as (2 * 12 + 5) / 12 = 29/12.

1 19/30 can be written as (1 * 30 + 19) / 30 =
