Ok so.....
1. We know that 2.25 is greater than 1, so it will be a mixed fraction
2. .25 ends in the hundredths place, meaning that 25 should be over 100, 25/100.
3. We converted .25 to 25/100, but we also have the 2, so it is now 2 25/100.
4. 2 25/100 can be simplified. The GCF (greatest common factor) is 4 so we divide the numerator and denominator by 4.
5. You should get 2 1/4 as your new fraction.
2.25 is 2 1/4 written as a fraction
