4. Component 4: Lesson Activity
Component 4A
Jane wants to practice her algebraic fraction skills. Her
teacher suggested she do some extra problems to help
consolidate her skills. Jane practiced and practiced lots of
questions until she could confidently simplify a number of
algebraic fractions into their simplest form.
6. Component 4C
After Jane completed these questions correctly, she
decided to do some more difficult questions to make sure she
really understood how to simplify algebraic fractions.

10. Component 4: Lesson Activity
Component 4A
Joe is a cook in a restaurant. Joes uses algebraic
expressions and formulate to determine many boxes of
vegetables he needs to buy to cook his meals each right. The
number of boxes of vegetables determines how much soup
he can cook.
On a particular night, Joe intends to make carrot soup.
The number of boxes Joe will need is determined by the
expression:
𝟑𝒙−𝟔
𝟓
−
𝟐𝒙+𝟏
𝟑
Where y is the number of boxes of carrots.

Q2. There are 51 people booked into the restaurant that
night. If each person has carrot soup how many boxes of
carrots will Joe require?
Q3. On a previous night, Joe purchased 125 boxes of
carrots. How many people was he expecting at the
restaurant?
12. Component 4C
