- 3
- 5
- 2
- 7 (Correct answer)
Correct answer: 7
The problem asks us to determine a quantity related to Liam's apples. Liam gives away 4 apples to his sister and 3 apples to his friend. To find the total number of apples he distributed, we add these amounts: 4 + 3 = 7 apples. Therefore, 7 represents the total quantity of apples Liam gave away.

- 11 cm²
- 22 cm²
- 24 cm² (Correct answer)
- 48 cm²
Correct answer: 24 cm²
The area of a rectangle is calculated by multiplying its length by its width. Given a length of 8 cm and a width of 3 cm, the calculation is 8 cm * 3 cm. This multiplication results in an area of 24 square centimeters.
Question 3: Sophie bought 3 packs of pencils. Each pack contains 6 pencils. How many pencils does Sophie have in total?
- 9
- 12
- 15
- 18 (Correct answer)
Correct answer: 18
To find the total number of pencils Sophie has, you need to multiply the number of packs by the number of pencils in each pack. Sophie bought 3 packs, and each pack contains 6 pencils. Therefore, 3 packs multiplied by 6 pencils per pack equals 18 pencils in total.
Question 4: What is the next number in the sequence: 2, 4, 8, 16, ___?
- 20
- 24
- 32 (Correct answer)
- 48
Correct answer: 32
This is a geometric sequence where each number is obtained by multiplying the previous number by 2. The pattern is 2 * 2 = 4, 4 * 2 = 8, and 8 * 2 = 16. Following this rule, the next number in the sequence is 16 * 2, which equals 32.
Question 5: A bakery sold 135 muffins in the morning and 87 muffins in the afternoon. How many muffins did the bakery sell in total?

To find the total number of muffins sold, you need to add the number of muffins sold in the morning to the number sold in the afternoon. The bakery sold 135 muffins in the morning and 87 muffins in the afternoon. Adding these two amounts together, 135 + 87, results in a total of 212 muffins sold.
