Is 5/7 greater than 6/8?
To compare two fractions, such as 5/7 and 6/8, 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 × 8 = 40
- Multiply the numerator of the second fraction with the denominator of the first fraction 6 × 7 = 42
- Multiply the denominators of both fractions together: 7 × 8 = 56
- Rewrite both fractions with the new common denominator:
- 5/7 = 40/56
- 6/8 = 42/56
With a common denominator, the comparison becomes much simpler.
Since 40 is smaller than 42, we can conclude that 5/7 is less than 6/8.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 5 divided by 7 is equal to 0.71428571428571
- 6 divided by 8 is equal to 0.75
Since 0.71428571428571 is smaller than 0.75, it means that 5/7 is less than 6/8.
