Is 2/3 greater than 5/7?
To compare two fractions, such as 2/3 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: 2 × 7 = 14
- Multiply the numerator of the second fraction with the denominator of the first fraction 5 × 3 = 15
- Multiply the denominators of both fractions together: 3 × 7 = 21
- Rewrite both fractions with the new common denominator:
- 2/3 = 14/21
- 5/7 = 15/21
With a common denominator, the comparison becomes much simpler.
Since 14 is smaller than 15, we can conclude that 2/3 is less than 5/7.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 2 divided by 3 is equal to 0.66666666666667
- 5 divided by 7 is equal to 0.71428571428571
Since 0.66666666666667 is smaller than 0.71428571428571, it means that 2/3 is less than 5/7.
