Is 8/5 greater than 2/7?
To compare two fractions, such as 8/5 and 2/7, 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: 8 × 7 = 56
- Multiply the numerator of the second fraction with the denominator of the first fraction 2 × 5 = 10
- Multiply the denominators of both fractions together: 5 × 7 = 35
- Rewrite both fractions with the new common denominator:
- 8/5 = 56/35
- 2/7 = 10/35
With a common denominator, the comparison becomes much simpler.
Since 56 is larger than 10, we can conclude that 8/5 is greater than 2/7.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 8 divided by 5 is equal to 1.6
- 2 divided by 7 is equal to 0.28571428571429
Since 1.6 is larger than 0.28571428571429, it means that 8/5 is greater than 2/7.
