Is 5/2 greater than 9/4?
To compare two fractions, such as 5/2 and 9/4, 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: 5 × 4 = 20
- Multiply the numerator of the second fraction with the denominator of the first fraction 9 × 2 = 18
- Multiply the denominators of both fractions together: 2 × 4 = 8
- Rewrite both fractions with the new common denominator:
- 5/2 = 20/8
- 9/4 = 18/8
With a common denominator, the comparison becomes much simpler.
Since 20 is larger than 18, we can conclude that 5/2 is greater than 9/4.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 5 divided by 2 is equal to 2.5
- 9 divided by 4 is equal to 2.25
Since 2.5 is larger than 2.25, it means that 5/2 is greater than 9/4.
