Here are the step-by-step solutions for each problem on the worksheet.
Problem 1
*
Step 1: Identify the numbers. There are 30 students per bus and 3 buses.
*
Step 2: Since we need to find the total number of students, we multiply the number of students by the number of buses.
*
Calculation: $30 \times 3 = 90$.
*
Check: $30 + 30 + 30 = 90$. The calculation is correct.
Problem 2
*
Step 1: Identify the numbers. Nancy spent $\$32$ total for 4 pencils.
*
Step 2: To find the cost of *one* pencil, we divide the total cost by the number of pencils.
*
Calculation: $32 \div 4 = 8$.
*
Check: If one pencil costs $\$8$, then 4 pencils cost $8 \times 4 = 32$. The calculation is correct.
Problem 3
*
Step 1: Identify the numbers. There are 12 seats in a row and 7 rows.
*
Step 2: To find the total number of seats, we multiply the seats per row by the number of rows.
*
Calculation: $12 \times 7$.
* $10 \times 7 = 70$
* $2 \times 7 = 14$
* $70 + 14 = 84$
*
Check: The multiplication is accurate.
Problem 4
*
Step 1: Identify the numbers. David has 50 biscuits for 5 days.
*
Step 2: He eats an equal amount each day, so we divide the total biscuits by the number of days.
*
Calculation: $50 \div 5 = 10$.
*
Check: If he eats 10 biscuits a day for 5 days, $10 \times 5 = 50$. The calculation is correct.
Final Answer:
1. 90 students
2. $8
3. 84 seats
4. 10 biscuits
