Answer 2

Let's solve the given expressions:

1. 3/4 + 3/5 + 1/3

To add fractions, we need to find a common denominator. The common denominator in this case is 60. So, we multiply the numerators and denominators by appropriate values to make the denominators equal:

(3/4) * (15/15) + (3/5) * (12/12) + (1/3) * (20/20) = 45/60 + 36/60 + 20/60

Now, we can add the fractions:

(45 + 36 + 20)/60 = 101/60

2. 2/3 + 4/5 + 2/4

In this case, the common denominator is 60:

(2/3) * (20/20) + (4/5) * (12/12) + (2/4) * (15/15) = 40/60 + 48/60 + 30/60

Adding the fractions:

(40 + 48 + 30)/60 = 118/60 = 59/30 (in simplified form)

3. 2/4 + 2/5 + 2/10

The common denominator is 20:

(2/4) * (5/5) + (2/5) * (4/4) + (2/10) * (2/2) = 10/20 + 8/20 + 4/20

Adding the fractions:

(10 + 8 + 4)/20 = 22/20 = 11/10

4. 7/10 + 2/3 + 1/5

The common denominator is 30:

(7/10) * (3/3) + (2/3) * (10/10) + (1/5) * (6/6) = 21/30 + 20/30 + 6/30

Adding the fractions:

(21 + 20 + 6)/30 = 47/30

5. 3/4 + 1/2 + 1/10

The common denominator is 20:

(3/4) * (5/5) + (1/2) * (10/10) + (1/10) * (2/2) = 15/20 + 10/20 + 2/20

Adding the fractions:

(15 + 10 + 2)/20 = 27/20 = 1 7/20 (in mixed number form)

6. 8/10 + 1/2 + 2/4

The common denominator is 4:

(8/10) * (2/2) + (1/2) * (4/4) + (2/4) * (1/1) = 16/20 + 4/20 + 2/4

Adding the fractions:

(16 + 4 + 2)/20 = 22/20 = 1 1/10 (in mixed number form)

7. 2/5 + 7/10 + 3/4

The common denominator is 20:

(2/5) * (4/4) + (7/10) * (2/2) + (3/4) * (5/5) = 8/20 + 14/20 + 15/20

Adding the fractions:

(8 + 14 + 15)/20 = 37/20 = 1 17/20 (in mixed number form)

8. 5/10 + 1/4 + 1/5

The common denominator is 20:

(5/10) * (2/2) + (1/4) * (5/5) + (1/5) * (4/4) = 10/20 + 5/20 + 4/20

Adding the fractions:

(10 + 5 + 4)/20 = 19/20

9. 4/5 + 4/10 + 1/2

The common denominator is 10:

(4/5) * (2/2) + (4/10) * (1/1) + (1/2) * (5/5) = 8/10 + 4/10 + 5/10

Adding the fractions:

(8 + 4 + 5)/10 = 17/10 = 1 7/10 (in mixed number form)

10. 3/5 + 3/4 + 6/10

The common denominator is 20:

(3/5) * (4/4) + (3/4) * (5/5) + (6/10) * (2/2) = 12/20 + 15/20 + 12/20

Adding the fractions:

(12 + 15 + 12)/20 = 39/20 = 1 19/20 (in mixed number form)
