[ 1/3 Fraction calculation ]
Question type: Fractional addition
Original question: 2/11+5/12
Solution:
2 11 | + | 5 12 |
Divide the least common multiple 132 by the denominator 11 of the first addend to get 12
Multiply the numerator 2 and denominator 11 of the first fraction by 12
Then divide the least common multiple 132 by the denominator 12 of the second addend to get 11
Multiply the numerator 5 and denominator 12 of the second fraction by 11
| = | 24 132 | + | 55 132 |
| = | 79 132 |
