Answer 3

Let's solve each of the equations step by step:

1. (2/6) + (3/4):

To add fractions with different denominators, we need to find a common denominator. In this case, the least common denominator (LCD) is 12. We can convert the fractions to have a denominator of 12:

(2/6) = (2/6) * (2/2) = 4/12 (3/4) = (3/4) * (3/3) = 9/12

Now, we can add the fractions:

(4/12) + (9/12) = (4 + 9) / 12 = 13/12

So, (2/6) + (3/4) = 13/12.

2. (7/3) - (2/5):

To subtract fractions, we again need a common denominator. The LCD for 3 and 5 is 15. We can convert the fractions:

(7/3) = (7/3) * (5/5) = 35/15 (2/5) = (2/5) * (3/3) = 6/15

Now, we can subtract the fractions:

(35/15) - (6/15) = (35 - 6) / 15 = 29/15

So, (7/3) - (2/5) = 29/15.

3. (1/2) * (3/4):

To multiply fractions, we simply multiply the numerators together and the denominators together:

(1/2) * (3/4) = (1 * 3) / (2 * 4) = 3/8

So, (1/2) * (3/4) = 3/8.

4. (2 1/6) + (3/4):

First, let's convert the mixed number to an improper fraction:

2 1/6 = (2 * 6 + 1) / 6 = 13/6

Now, we need a common denominator to add the fractions. The LCD for 6 and 4 is 12. Converting the fractions:

(13/6) = (13/6) * (2/2) = 26/12 (3/4) = (3/4) * (3/3) = 9/12

Now, we can add the fractions:

(26/12) + (9/12) = (26 + 9) / 12 = 35/12

So, (2 1/6) + (3/4) = 35/12.

To summarize:

1. (2/6) + (3/4) = 13/12
2. (7/3) - (2/5) = 29/15
3. (1/2) * (3/4) = 3/8
4. (2 1/6) + (3/4) = 35/12
