8/9 + 2/5

In order to add or subtract fractions, the denominators of each fraction must be the same. The common denominator for both fractions to be added is 45. So you must multiply the given fractions by a fraction that is equal to the number one, and will give the denominator as 45. For 8/9, the fraction 5/5 is equal to one and when multiplied times 8/9 gives the denominator of 45. For 2/5, the fraction 9/9 is equal to one and when multiplied times 2/5 gives the denominator of 45.

8/9 x 5/5 = 40/45

2/5 x 9/9 = 18/45

Once you have all your fractions with the same denominators, you can add them.

8/9 + 2/5 = 40/45 + 18/45 = 58/45

58/45 = 1 13/45
