Answer 2

a) 1 3/4 - 1/8: To subtract fractions, we need to have a common denominator. In this case, the common denominator is 8. So, we need to convert 1 3/4 into an equivalent fraction with a denominator of 8.

1 3/4 = (4 * 1 + 3) / 4 = 7/4

Now, we can subtract the fractions:

7/4 - 1/8 = (7 * 2 - 1) / 8 = 13/8

So, the answer is 13/8.

b) 4 1/3 + 1/6: To add fractions, we need to have a common denominator. In this case, the common denominator is 6. So, we need to convert 4 1/3 into an equivalent fraction with a denominator of 6.

4 1/3 = (3 * 4 + 1) / 3 = 13/3

Now, we can add the fractions:

13/3 + 1/6 = (13 * 2 + 1) / 6 = 27/6

We can simplify this fraction by dividing the numerator and denominator by their greatest common divisor, which is 3:

27/6 = (9 * 3) / (2 * 3) = 9/2

So, the answer is 9/2.

c) 5 1/4 - 2 1/3: To subtract fractions, we need to have a common denominator. In this case, the common denominator is 12. So, we need to convert 5 1/4 and 2 1/3 into equivalent fractions with a denominator of 12.

5 1/4 = (4 *
