Evaluate the expression shown below and write your answer as a fraction in simplest form - 3/16 + ( - 11/20)

Answer 1

To add these fractions, we need to find a common denominator. The smallest number that 16 and 20 both divide evenly into is 80.

First, we need to convert 3/16 to have a denominator of 80:
3/16 * 5/5 = 15/80

Next, we need to convert -11/20 to have a denominator of 80:
-11/20 * 4/4 = -44/80

Now, we can add the fractions:
15/80 + (-44/80)

To add fractions, we simply add the numerators when the denominators are the same:
15 - 44 = -29
80

So, the answer is -29/80.
