Answer 2

Let's simplify each of these expressions step by step:

1. 3/4 + 3/5 + 1/3.2

To add fractions, you need a common denominator. In this case, the common denominator is 20 (4 * 5). So, you need to rewrite each fraction with a denominator of 20:

(15/20) + (12/20) + (5/20)

Now, you can add the fractions:

15/20 + 12/20 + 5/20 = (15 + 12 + 5) / 20 = 32/20

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4:

(32/4) / (20/4) = 8/5

So, the result is 8/5.

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

First, find a common denominator, which in this case is 15 (3 * 5):

(10/15) + (12/15) + (7/15)

Now, add the fractions:

10/15 + 12/15 + 7/15 = (10 + 12 + 7) / 15 = 29/15

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

Find a common denominator, which in this case is 30 (10 * 3):

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

Now, add the fractions:

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

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

Find a common denominator, which in this case is 20 (4 * 5):

(15/20) + (10/20) + (2/20)

Now, add the fractions:

15/20 + 10/20 + 2/20 = (15 + 10 + 2) / 20 = 27/20

So, the simplified results are:

1. 8/5
2. 29/15
3. 47/30
4. 27/20
