Is 2/7 greater than 7/2?
To compare two fractions, such as 2/7 and 7/2, 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 × 2 = 4
- 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 × 2 = 14
- Rewrite both fractions with the new common denominator:
- 2/7 = 4/14
- 7/2 = 49/14
With a common denominator, the comparison becomes much simpler.
Since 4 is smaller than 49, we can conclude that 2/7 is less than 7/2.
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 2 is equal to 3.5
Since 0.28571428571429 is smaller than 3.5, it means that 2/7 is less than 7/2.
