2 equal parts
8 equal parts
4 equal parts
mushroom
pepperoni
cheese

1. mr. yung puts onions on \\(\frac{1}{2}\\) of the mushroom pizza. shade the amount of pizza that has onions.
2. rose eats 1 equal part that mr. yung cut from a pizza. she has eaten \\(\frac{1}{8}\\) of the whole pizza. which pizza did rose eat?

Explanation:

Step1: Solve Q7: Divide pizzas as required

• Mushroom pizza: Draw 1 straight line through the center to split into 2 equal parts.
• Pepperoni pizza: Draw 4 straight lines through the center, dividing the circle into 8 equal angular slices (each slice = $360^\circ/8 = 45^\circ$).
• Cheese pizza: Draw 2 perpendicular straight lines through the center to split into 4 equal parts.

Step2: Solve Q8: Shade 1/2 of mushroom pizza

The mushroom pizza is split into 2 equal parts. Shade 1 of the 2 parts, which represents $\frac{1}{2}$ of the whole pizza.

Step3: Solve Q9: Match slice to pizza

1. For a pizza cut into $n$ equal parts, 1 slice = $\frac{1}{n}$ of the whole pizza.
2. Set $\frac{1}{n} = \frac{1}{8}$, so $n=8$.
3. The pepperoni pizza is cut into 8 equal parts.

Answer:

7.

• Mushroom pizza: 1 straight line through the center creating 2 equal halves.
• Pepperoni pizza: 4 lines through the center creating 8 equal slices.
• Cheese pizza: 2 perpendicular lines through the center creating 4 equal quarters.

1. Shade 1 of the 2 equal parts of the mushroom pizza.
2. Pepperoni pizza
