Answer:
Let's start by finding out how many muffins were there in total before the ogre stole 20 of them. Let's call that number "x".
If 5/8 of them were left after the ogre stole 20, then 3/8 of them were taken.
So we can set up an equation:
x - 20 = 3/8x
To solve for x, we can start by multiplying both sides by 8 to get rid of the fraction:
8(x - 20) = 3x
8x - 160 = 3x
Now we can solve for x by subtracting 3x from both sides:
5x - 160 = 0
5x = 160
x = 32
So there were originally 32 muffins.
Now we can find out how many are left:
5/8 of 32 = 20
So there are 20 muffins left.
