if 1/4 is eaten. that means 3/4 is still there. If 2/5 is eaten of the 3/4 that remains that means 3/5 remains of that 3/4.

3/4 x 3/5 = 9/20

it's pie, not pai

lot's of different answers here. the way you have it worded, it could mean two things. Do you mean eating 2/5 of what remained after I ate the 1/4 or do you mean 2/5 of a whole pie. I already did scenario 1. If you mean scenario 2, here...

1 - 1/4 - 2/5 =

20/20 - 5/20 - 8/20 = 7/20

1/4 is eaten

Remainder = 3/4

(2/5) (3/4) = 3/10 is then eaten

Total eaten is 1/4 + 3/10 = 5/20 + 6/20 = 11/20

Remainder = 9/20

im answering because like no one got the same answer so ill tell you the correct answer...

            1/4 + 2/5 = 5/20 + 8/20 = 20/20 - 13/30 = the answer is 7/20

               7/20 IS the CORRECT answer.....................

1/4 + 2/5 + X = 1

3/9 + X = 1

  X=1 - 3/9

  X= 9/9 - 3/9

  X = 6/9

THEN THE REMAINING IS 6/9 THAT IS IF THE 2/5 IS EATEN FROM THE SAME BEGINNING UNIT AND NOT FROM THE REMAINING.

1 - 1/4 - 2/5

= 20/20 - 5/20 - 8/20 = 7/20

"pie"

a lot of strange answers for a simple problem, but because there is an ambiguity in the question.

Two possibilities, I'll do both

Case 1: "if 1/4 of a pie is eaten and later 2/5 (of the entire pie) is eaten, what is the remaining fraction?"

1 - 1/4 - 2/5

LCD

20/20 - 5/20 - 8/20

7/20 <<< ans1

Case 2: "if 1/4 of a pie is eaten and later 2/5 (of the remainder) is eaten, what is the remaining fraction?"

step 1, remove 1/4 and you get 3/4 of a pie left

step 2, 2/5 of the remainder is 2/5 * 3/4 = 3/10 eaten from the whole

step 3, get the total left

1 - 1/4 - 3/10

20/20 - 5/20 - 6/20

9/20 <<< ans2

3/4 is left after you eat 1/4, right?

So, (3/4) minus (2/5) would give you the remaining portion.

If you do that on your calculator, you'd enter .75 - .4 and you'd get .35

Or, in a fraction, 7/20

1/4+2/5

5/20+8/20

= 13/20

First time there is 3/4 remaining

Of the 3/4 remaining, 3/5 is left after the second round

or 3/4 x 3/5 = 9/20  if you mean 2/5 of what was left over

if you mean 2/5 of the original pie then

what was eaten is 1/4 + 2/5   = 13/20

which means that 7/20 remains
