Answer:
Taki is correct
Step-by-step explanation:
5/4 is an improper fraction, and when you turn it into a mixed fraction it'll be 1 1/4 because if you take out 4/4 out of 5/4 it'll make a whole number and you'll have one left which will make it 1 1/4. So Taki is correct and Yoko is incorrect.
If that makes sense.
