reduce sum to lowest terms whenever possible 4/7+3/21+4/14

4/7 + 3/21 + 4/14 = 24/42 + 6/42 + 12/ 42 = 42/42 or 1
You may first reduce each fraction to lowest term:
4/7 = 4/7 (lowest term)
3/21 = 1/7 (lowest term)
4/14 = 2/7 ( lowest term)

Notice that they have the same denominators in the lowest term and are now similar terms, so add the numerators.

4/7 + 1/7 + 2/7 = 7/7  or 1
