Question

Evaluate the expression shown below and write your answer as a fraction in simplest form 3/8 + 11/20

Answer 1

37/40

Explanation:

1. Find the LCM (Lowest Common Denominator, this allows us to actually add the two fractions together).

3/8 = 15/40

11/20 = 22/40

The numbers 8 and 20 both share the number 40 in this case.

2. Add the numbers together, then simplify.

15/40 + 22/40 = 37/40

Fortunately for us, 37/40 is already simplified.

There you go!
