3. How many eighths are there in 4 ³⁄₈?

Answer:

📖 REMINDER: Convert the mixed number to an improper fraction with the given denominator. The numerator tells you how many of that fractional part (e.g., eighths) there are.

4. A baker made 15 litres of lemonade for a fair. He poured the lemonade equally into 36 cups.
How many litres of lemonade were there in each cup? Give your answer as a fraction in the
simplest form.

Answer: litres

📖 REMINDER: To share equally, divide the total amount by the number of parts. Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD).

5. On Monday, Priya cycled for a distance of 6 ²⁄₃ km. She cycled 1 ³⁄₄ km shorter on Monday than on Tuesday.
How far did she cycle on Tuesday? Give your answer as a mixed number.

7. In the number line below, what is the mixed number represented by point B? Give your answer in the simplest form.

Answer:

📖 REMINDER: Count the number of equal parts between whole numbers to determine the denominator. The position of the point within that interval gives the numerator.

10. The first 18 numbers of a number pattern are given below.
4, 1, 6, 3, 2, 4, 1, 6, 3, 2, 4, 1, 6, 3, 2, 4, 1, 6 ...
What is the sum of the first 97 numbers?

Answer:

📖 REMINDER: First identify the repeating cycle and its length. Then find how many complete cycles fit into the total count, calculate the sum for complete cycles, and add any partial cycle remainder.

11. Emma had some strawberry and blueberry muffins. She sold ³⁄₅ of the strawberry muffins and ²⁄₉ of the blueberry muffins.
⁵⁄₈ of the muffins sold were strawberry muffins. What fraction of all the muffins did she sell altogether?

Answer: 

📖 REMINDER: Use the unit method. Assign units to the original quantities. The relationship between the sold quantities gives an equation to find the ratio between the two types.

12. Priya, Ravi, and Sam had a total of 924 stamps at first. They used the same number of stamps for a project.
Priya used ⁴⁄₇ of her stamps, Ravi used ³⁄₅ of his stamps, and Sam used ¹⁄₃ of his stamps.
How many stamps did they use altogether for the project?

Answer:

📖 REMINDER: Since they used the same number of stamps, the fractions tell us the relationship between their original stamp counts. Use the unit method with a common value for the stamps used.

13. The table shows the prices of tickets for a museum.
The number of student tickets sold was ³⁄₇ of the number of adult tickets sold.
¹⁄₈ of the tickets sold were senior citizen tickets. A total of $6340 was collected from the sale of tickets.

(a) What fraction of the tickets sold were student tickets?

Answer:

(b) What was the total number of tickets sold?

Answer: 

📖 REMINDER: Use the unit method. First find the ratio of adult:student:senior tickets. Then use the total money collected to find the value of one unit.
