To find out how many extra cups John put in the cupcakes, we should first find the difference between the original amount specified in the recipe and the amount John actually put in.
Original amount of flour = 3 and 3/10 cups = 3 + 3/10 = 30/10 + 3/10 = 33/10 cups
Amount John put in = 3 and 5/8 cups = 3 + 5/8 = 24/8 + 5/8 = 29/8 cups
Now, let's calculate the extra amount John put in:
Extra amount = Amount John put in - Original amount of flour
Extra amount = 29/8 - 33/10
To subtract these fractions, we need to find a common denominator, which is 40.
Extra amount = (29/8) * (5/5) - (33/10) * (4/4)
Extra amount = 145/40 - 132/40
Extra amount = (145 - 132)/40
Extra amount = 13/40 cups
Therefore, John accidentally put in an extra 13/40 cups of flour in the cupcakes.
