Is 2/7 greater than 7/5?
To compare two fractions, such as 2/7 and 7/5, 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: 2 × 5 = 10
- Multiply the numerator of the second fraction with the denominator of the first fraction 7 × 7 = 49
- Multiply the denominators of both fractions together: 7 × 5 = 35
- Rewrite both fractions with the new common denominator:
- 2/7 = 10/35
- 7/5 = 49/35
With a common denominator, the comparison becomes much simpler.
Since 10 is smaller than 49, we can conclude that 2/7 is less than 7/5.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 2 divided by 7 is equal to 0.28571428571429
- 7 divided by 5 is equal to 1.4
Since 0.28571428571429 is smaller than 1.4, it means that 2/7 is less than 7/5.
