Step 2: Calculate the number of pieces you ate.
- Multiply the fraction (3/5) by the total number of pieces (20).
- (3/5) * 20 = 12.

Therefore, you ate 12 pieces of the cake.

To find out how many pieces you ate, you need to calculate 3/5 of the total number of pieces.

First, you need to find out what 3/5 of 20 is. To do that, you can multiply 20 by the fraction 3/5:

(20 * 3/5) = 60/5 = 12
