Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

29 - (37x) 29 - 37x

—————————— = ————————

10 10

(29 - 37x)

—————————— + 5

10

Adding a whole to a fraction

Rewrite the whole as a fraction using 10 as the denominator :

5 5 • 10

5 = — = ——————

1 10

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(29-37x) + 5 • 10 79 - 37x

————————————————— = ————————
