Is 9/7 greater than 4/5?
To compare two fractions, such as 9/7 and 4/5, 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: 9 × 5 = 45
- Multiply the numerator of the second fraction with the denominator of the first fraction 4 × 7 = 28
- Multiply the denominators of both fractions together: 7 × 5 = 35
- Rewrite both fractions with the new common denominator:
- 9/7 = 45/35
- 4/5 = 28/35
With a common denominator, the comparison becomes much simpler.
Since 45 is larger than 28, we can conclude that 9/7 is greater than 4/5.
