Question 1

A number is divisible by both 4 and 6. Which of the following must also divide this number?

Accepted Answer

Step 1: A number divisible by both 4 and 6 must be divisible by their LCM. Step 2: Find LCM(4, 6): 4 = 2², 6 = 2 × 3, so LCM = 2² × 3 = 12. Step 3: Any number divisible by 12 is also divisible by 12 itself, as well as all its factors (1, 2, 3, 4, 6, 12). Therefore, the answer is 12.

Question 2

Simplify: 48 ÷ 6 + 12 × 2 − 5

Accepted Answer

Step 1: Apply BODMAS — Division and Multiplication first (left to right). 48 ÷ 6 = 8 and 12 × 2 = 24. Step 2: Now we have 8 + 24 − 5. Step 3: Addition and Subtraction (left to right): 8 + 24 = 32, then 32 − 5 = 27.

Question 3

Simplify: 2 + 8 × 5 − 12 ÷ 3

Accepted Answer

Step 1: Apply BODMAS — Multiplication and Division first (left to right). 8 × 5 = 40 and 12 ÷ 3 = 4. Step 2: Now we have 2 + 40 − 4. Step 3: Addition and Subtraction (left to right): 2 + 40 = 42, then 42 − 4 = 38.

Question 4

What is the value of 36 + 12 ÷ 4 − 3 × 2?

Accepted Answer

Step 1: Apply BODMAS — Division and Multiplication first (left to right). 12 ÷ 4 = 3 and 3 × 2 = 6. Step 2: Now we have 36 + 3 − 6. Step 3: Addition and Subtraction (left to right): 36 + 3 = 39, then 39 − 6 = 33.

Question 5

Calculate: 60 ÷ 5 × 2 + 10 − 8

Accepted Answer

Step 1: Apply BODMAS — Division and Multiplication first (left to right). 60 ÷ 5 = 12, then 12 × 2 = 24. Step 2: Now we have 24 + 10 − 8. Step 3: Addition and Subtraction (left to right): 24 + 10 = 34, then 34 − 8 = 26.
