Answer 3

To solve the expressions, we'll perform the necessary arithmetic operations. Let's calculate each one step by step:

1. -3/8 + 3/4: To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 8.

-3/8 + 3/4 = -3/8 + (3/4) * (2/2) = -3/8 + 6/8 = (6 - 3)/8 = 3/8.

Therefore, -3/8 + 3/4 equals 3/8.

2. 3 5/14 + (-45/7): First, we need to convert the mixed number into an improper fraction.

3 5/14 = (3 * 14 + 5)/14 = 47/14.

Now we can add the fractions. To do so, we need to find a common denominator, which in this case is 14.

47/14 + (-45/7) = (47/14) + (-45/7) * (2/2) = 47/14 + (-90/14) = (47 - 90)/14 = -43/14.

Therefore, 3 5/14 + (-45/7) equals -43/14.
