Is 7/8 greater than 2/7?
To compare two fractions, such as 7/8 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: 7 × 7 = 49
- Multiply the numerator of the second fraction with the denominator of the first fraction 2 × 8 = 16
- Multiply the denominators of both fractions together: 8 × 7 = 56
- Rewrite both fractions with the new common denominator:
- 7/8 = 49/56
- 2/7 = 16/56
With a common denominator, the comparison becomes much simpler.
Since 49 is larger than 16, we can conclude that 7/8 is greater than 2/7.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 7 divided by 8 is equal to 0.875
- 2 divided by 7 is equal to 0.28571428571429
Since 0.875 is larger than 0.28571428571429, it means that 7/8 is greater than 2/7.
