Since 8 is evenly divided by 16, we can multiply just one term to get a common denominator.

You are watching: 7 8 7 16 reduced to lowest terms

Multiply 7 by 2, and get 14, then we multiply 8 by 2 and get 16.

*

The problem now has new fractions to add:

7
16
+14
16

Step 2

Since our denominators match, we can add the numerators.

7 + 14 = 21

The sum we get is

21
16

Step 3

The last step is to reduce the fraction if we can.

To find out, we try dividing it by 2...
