2/3 is the originonal fraction for w suger
1. 2 1/2
2. 2 1/4
3. 5 5/8
4. 5 1/4

Answer 1

It is 5 5/8 because you have to change them both into improper fractions so 2 1/2 turns into 5/2 and 2 1/4 changes to 9/4 so you have 5/2 * 9/4 but you need to be able to multiply them so the 5/2 changes to 10/4 so 9/4 * 10/4 = 5 5/8 :)
