Is 3/2 greater than 9/4?
To compare two fractions, such as 3/2 and 9/4, 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: 3 × 4 = 12
- Multiply the numerator of the second fraction with the denominator of the first fraction 9 × 2 = 18
- Multiply the denominators of both fractions together: 2 × 4 = 8
- Rewrite both fractions with the new common denominator:
- 3/2 = 12/8
- 9/4 = 18/8
With a common denominator, the comparison becomes much simpler.
Since 12 is smaller than 18, we can conclude that 3/2 is less than 9/4.
2) Converting to decimal
We can also simply convert the fractions into decimal values:
- 3 divided by 2 is equal to 1.5
- 9 divided by 4 is equal to 2.25
Since 1.5 is smaller than 2.25, it means that 3/2 is less than 9/4.
