38 211 | + | 64 137 |
Divide the least common multiple 28907 by the denominator 211 of the first addend to get 137
Multiply the numerator 38 and denominator 211 of the first fraction by 137
Then divide the least common multiple 28907 by the denominator 137 of the second addend to get 211
Multiply the numerator 64 and denominator 137 of the second fraction by 211
| = | 5206 28907 | + | 13504 28907 |
| = | 18710 28907 |
