Is 5/7 greater than 1/2?
To compare two fractions, such as 5/7 and 1/2, 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: 5 × 2 = 10
- Multiply the numerator of the second fraction with the denominator of the first fraction 1 × 7 = 7
- Multiply the denominators of both fractions together: 7 × 2 = 14
- Rewrite both fractions with the new common denominator:
- 5/7 = 10/14
- 1/2 = 7/14
With a common denominator, the comparison becomes much simpler.
Since 10 is larger than 7, we can conclude that 5/7 is greater than 1/2.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 5 divided by 7 is equal to 0.71428571428571
- 1 divided by 2 is equal to 0.5
Since 0.71428571428571 is larger than 0.5, it means that 5/7 is greater than 1/2.
