Original question: 112/210+30/7
Solution:
112 210 | + | 30 7 |
| = | 8 15 | + | 30 7 |
| = | 8 15 | + | 30 7 |
Divide the least common multiple 105 by the denominator 15 of the first addend to get 7
Multiply the numerator 8 and denominator 15 of the first fraction by 7
Then divide the least common multiple 105 by the denominator 7 of the second addend to get 15
Multiply the numerator 30 and denominator 7 of the second fraction by 15
| = | 56 105 | + | 450 105 |
| = | 506 105 |
