Is 5/2 greater than 8/5?
To compare two fractions, such as 5/2 and 8/5, 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: 5 × 5 = 25
- Multiply the numerator of the second fraction with the denominator of the first fraction 8 × 2 = 16
- Multiply the denominators of both fractions together: 2 × 5 = 10
- Rewrite both fractions with the new common denominator:
- 5/2 = 25/10
- 8/5 = 16/10
With a common denominator, the comparison becomes much simpler.
Since 25 is larger than 16, we can conclude that 5/2 is greater than 8/5.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 5 divided by 2 is equal to 2.5
- 8 divided by 5 is equal to 1.6
Since 2.5 is larger than 1.6, it means that 5/2 is greater than 8/5.
