Answer 3

According to the information provided, Shynar bought a chocolate bar that is divided into 20 equal pieces. Let's answer the questions step by step.

a) Shynar ate 5 pieces of chocolate. To find out what fraction of the chocolate she ate, we need to divide the number of pieces she ate by the total number of pieces in the chocolate bar. In this case, it would be 5/20, which simplifies to 1/4. So Shynar ate 1/4 of the chocolate bar.

b) Later in the same day, Shynar ate 3/5 of the remaining chocolate. To calculate the total number of pieces she ate, we need to find out how many pieces were left after she ate 5 pieces. Since she ate 1/4 of the chocolate bar, there were 3/4 of the chocolate bar left. Multiplying 3/4 by 20 (the total number of pieces) gives us 15 pieces.

Then, Shynar ate 3/5 of the remaining 15 pieces. To find out how many pieces she ate, we multiply 3/5 by 15, which gives us 9 pieces.

Therefore, Shynar ate a total of 5 + 9 = 14 pieces of chocolate.

I hope this helps! Let me know if you have any further questions.
