[ 1/4 Fraction calculation ]
Question type: Fractional multiplication
Original question: 4/9*9/16
Solution:
4 9 | × | 9 16 |
| = | 1 9 | × | 4 |

| = | 1 | × | 1 4 |
| = | 1 | × | 1 4 |
| = | 1 4 |
[ 2/4 Fraction calculation ]
Question type: Fractional addition
Original question: 1/2+1/3
Solution:
1 2 | + | 1 3 |
Divide the least common multiple 6 by the denominator 2 of the first addend to get 3
Multiply the numerator 1 and denominator 2 of the first fraction by 3
Then divide the least common multiple 6 by the denominator 3 of the second addend to get 2
Multiply the numerator 1 and denominator 3 of the second fraction by 2
| = | 3 6 | + | 2 6 |
| = | 5 6 |
