Original question: 210/112+30/7
Solution:
210 112 | + | 30 7 |
| = | 15 8 | + | 30 7 |
| = | 15 8 | + | 30 7 |
Divide the least common multiple 56 by the denominator 8 of the first addend to get 7
Multiply the numerator 15 and denominator 8 of the first fraction by 7
Then divide the least common multiple 56 by the denominator 7 of the second addend to get 8
Multiply the numerator 30 and denominator 7 of the second fraction by 8
| = | 105 56 | + | 240 56 |
| = | 345 56 |
