Julio

Step-by-step explanation:

julio in 4 minutes does 128 : 4 equals 32 half of 64 if Julio had gotten 8 minutes he would have done 256 sit-ups

Holly was already because Fred did more in the same amount of time Olivia did to little in more than half the time

Julio = 32 per minute

Step-by-step explanation:

Fred = 243 / 9 = 27

Julio = 128 / 4 = 32

Holly = 144 / 9 = 16

Olivia = 60 / 5 = 12
