7 9 | + | 13 16 |
Divide the least common multiple 144 by the denominator 9 of the first addend to get 16
Multiply the numerator 7 and denominator 9 of the first fraction by 16
Then divide the least common multiple 144 by the denominator 16 of the second addend to get 9
Multiply the numerator 13 and denominator 16 of the second fraction by 9
| = | 112 144 | + | 117 144 |
| = | 229 144 |
