Answer:
Step-by-step explanation:
8 kg of mash potato
2/5 ate
So you'll need to do 8*2/5
Step 1: Divide 8 by 5, 8/5=1.6 kg
1.6 kg=1/5 of mashed potato cooked
Multiply by 2 as 2 parts eaten.
1.6*2= 3.2 kg of mashed potato cooked
3.2 kg= 2/5 of potato eaten
Therefore, only 3.2 kg of mashed potato have been eaten
