Is 9/4 greater than 5/7?
To compare two fractions, such as 9/4 and 5/7, 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 × 7 = 63
- Multiply the numerator of the second fraction with the denominator of the first fraction 5 × 4 = 20
- Multiply the denominators of both fractions together: 4 × 7 = 28
- Rewrite both fractions with the new common denominator:
- 9/4 = 63/28
- 5/7 = 20/28
With a common denominator, the comparison becomes much simpler.
Since 63 is larger than 20, we can conclude that 9/4 is greater than 5/7.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 9 divided by 4 is equal to 2.25
- 5 divided by 7 is equal to 0.71428571428571
Since 2.25 is larger than 0.71428571428571, it means that 9/4 is greater than 5/7.
