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