3/5

ANSWER:

Jack picked 10 ears of corn. The amount of corn left is ears of initial corn.

SOLUTION:

Given, Jack picked 10 ears of corn.  

Now the total corn present is 10 ears.

He and two of his sisters ate two each.

Then, remaining corn = 10 ears – eaten corn

= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)

= 10 – 6  = 4  

Now, the amount of corn left in fraction is remaining corn divided by initial corn.

Left over corn =

Hence, the amount of corn left is ears of initial corn.
