Is 4/5 greater than 7/8?
To compare two fractions, such as 4/5 and 7/8, 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: 4 × 8 = 32
- Multiply the numerator of the second fraction with the denominator of the first fraction 7 × 5 = 35
- Multiply the denominators of both fractions together: 5 × 8 = 40
- Rewrite both fractions with the new common denominator:
- 4/5 = 32/40
- 7/8 = 35/40
With a common denominator, the comparison becomes much simpler.
Since 32 is smaller than 35, we can conclude that 4/5 is less than 7/8.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 4 divided by 5 is equal to 0.8
- 7 divided by 8 is equal to 0.875
Since 0.8 is smaller than 0.875, it means that 4/5 is less than 7/8.
