A piece of ribbon is 𝑦 cm long. Ashley cut it into 4 equal pieces
to do her 4 sisters’ hair. Write the expression for the amount of
ribbon used for each sister.

To determine the amount of ribbon used for each sister, we need to divide the total length of the ribbon by the number of pieces it is cut into.

Given:
- The total length of the ribbon is \( y \) cm.
- The ribbon is cut into 4 equal pieces.

To find the length of each piece, we divide \( y \) by 4:

\[
\text{Length of ribbon for each sister} = \frac{y}{4}
\]

So, the expression for the amount of ribbon used for each sister is:

\[
\frac{y}{4} \text{ cm}
\]

2. What happens to the length of each piece if the ribbon is cut into 5 pieces instead of 4?
3. How can we find the total ribbon length used if each sister receives 3 cm of ribbon?
4. If Ashley uses 2 pieces of ribbon for each sister, what is the total length of ribbon used?
5. How would you express the amount of ribbon left if each sister gets 5 cm, and \( y = 30 \) cm?

### Tip:
To solve problems involving division of quantities, always check the total amount divided by the number of groups to find the size of each group.
