Is 4/7 greater than 8/9?
To compare two fractions, such as 4/7 and 8/9, there are two main common methods: the first one involves finding a common denominator, and the other one is to convert the fractions directly into decimal values.
1) Using the same denominator
- Multiply the numerator of the first fraction with the denominator of the second fraction: 4 × 9 = 36
- Multiply the numerator of the second fraction with the denominator of the first fraction 8 × 7 = 56
- Multiply the denominators of both fractions together: 7 × 9 = 63
- Rewrite both fractions with the new common denominator:
- 4/7 = 36/63
- 8/9 = 56/63
With a common denominator, the comparison becomes much simpler.
Since 36 is smaller than 56, we can conclude that 4/7 is less than 8/9.
