Is 5/7 greater than 2/10?
To compare two fractions, such as 5/7 and 2/10, 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 × 10 = 50
- Multiply the numerator of the second fraction with the denominator of the first fraction 2 × 7 = 14
- Multiply the denominators of both fractions together: 7 × 10 = 70
- Rewrite both fractions with the new common denominator:
- 5/7 = 50/70
- 2/10 = 14/70
With a common denominator, the comparison becomes much simpler.
Since 50 is larger than 14, we can conclude that 5/7 is greater than 2/10.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 5 divided by 7 is equal to 0.71428571428571
- 2 divided by 10 is equal to 0.2
Since 0.71428571428571 is larger than 0.2, it means that 5/7 is greater than 2/10.
