Answer 3

A) To subtract the fractions 1 1/2 and 1 2, we need to convert them into a common denominator.

First, we convert 1 1/2 into an improper fraction: 1 1/2 = (1 * 2 + 1)/2 = 3/2

Now, we can subtract the fractions: 3/2 - 1 2

To subtract a mixed number from a fraction, we need to convert the mixed number into an improper fraction as well.

1 2 = (1 * 2 + 2)/2 = 4/2

Now we can subtract the fractions: 3/2 - 4/2 = (3 - 4)/2 = -1/2

Therefore, 1 1/2 - 1 2 = -1/2.

B) To subtract the fractions 1 1/5 and 2/5, we need to convert them into a common denominator.

First, we convert 1 1/5 into an improper fraction: 1 1/5 = (1 * 5 + 1)/5 = 6/5

Now we can subtract the fractions: 6/5 - 2/5 = (6 - 2)/5 = 4/5

Therefore, 1 1/5 - 2/5 = 4/5.
