Question type: Fractional addition
Original question: 4/10+8/22
Solution:
4 10 | + | 8 22 |
| = | 2 5 | + | 8 22 |
The second fraction is reduced by 2
| = | 2 5 | + | 4 11 |
| = | 2 5 | + | 4 11 |
Divide the least common multiple 55 by the denominator 5 of the first addend to get 11
Multiply the numerator 2 and denominator 5 of the first fraction by 11
Then divide the least common multiple 55 by the denominator 11 of the second addend to get 5
Multiply the numerator 4 and denominator 11 of the second fraction by 5
| = | 22 55 | + | 20 55 |
| = | 42 55 |
