☆5 fraction calculations
[ 1/5 Fraction calculation ]
Question type: Fractional addition
Original question: 3/10+2/15
Solution:
3 10 | + | 2 15 |
Divide the least common multiple 30 by the denominator 10 of the first addend to get 3
Multiply the numerator 3 and denominator 10 of the first fraction by 3
Then divide the least common multiple 30 by the denominator 15 of the second addend to get 2
Multiply the numerator 2 and denominator 15 of the second fraction by 2
| = | 9 30 | + | 4 30 |
| = | 13 30 |
[ 2/5 Fraction calculation ]
Question type: Fractional addition
Original question: 5/16+3/4
Solution:
5 16 | + | 3 4 |
Divide the least common multiple 16 by the denominator 16 of the first addend to get 1
Multiply the numerator 5 and denominator 16 of the first fraction by 1
Then divide the least common multiple 16 by the denominator 4 of the second addend to get 4
Multiply the numerator 3 and denominator 4 of the second fraction by 4
| = | 5 16 | + | 12 16 |
| = | 17 16 |
[ 3/5 Fraction calculation ]
Question type: Fractional subtraction
Original question: 3/5-7/15
Solution:
3 5 | － | 7 15 |
Divide the least common multiple 15 by the denominator 5 of the minuend to get 3
Multiply the numerator 3 and denominator 5 of the subtracted number by 3
Then divide the least common multiple 15 by the denominator 15 of the subtraction to get 1
Multiply the subtracted numerator 7 and denominator 15 by 1 at the same time
| = | 9 15 | － | 7 15 |
| = | 2 15 |
[ 4/5 Fraction calculation ]
Question type: Fractional addition
Original question: 4/13+9/52
Solution:
4 13 | + | 9 52 |
Divide the least common multiple 52 by the denominator 13 of the first addend to get 4
Multiply the numerator 4 and denominator 13 of the first fraction by 4
Then divide the least common multiple 52 by the denominator 52 of the second addend to get 1
Multiply the numerator 9 and denominator 52 of the second fraction by 1
| = | 16 52 | + | 9 52 |
| = | 25 52 |
[ 5/5 Fraction calculation ]
Question type: Fractional subtraction
Original question: 3/3-1/8
Solution:
3 3 | － | 1 8 |
| = | 1 1 | - | 1 8 |
| = | 1 | - | 1 8 |
Divide the least common multiple 8 by the denominator 1 of the minuend to get 8
Multiply the numerator 1 and denominator 1 of the subtracted number by 8
Then divide the least common multiple 8 by the denominator 8 of the subtraction to get 1
Multiply the subtracted numerator 1 and denominator 8 by 1 at the same time
| = | 8 8 | － | 1 8 |
| = | 7 8 |
