Goal: Apply what you have learned about dividing by 10 to solve word problems.
When you divide by 10, you need to remember your multiplication facts as well. If you know that 10 \({ \times }\) 7 \({ = }\) 70, you can also know that 70 \({ \div }\) 10 \({ = }\) 7.
Let’s practice using our multiplication facts to find the quotients in the following division sentences. Remember to use these problem-solving steps to help you find the answers to word problems.
Word Problem Solving Steps
- Read the problem.
- Look for important information.
- Write a math sentence.
- Choose a way to solve.
- Solve and label your answer.
Write a division sentence for the following problem.
Mary and Susan are completing a puzzle. It has 100 pieces and is 10 pieces wide. How many pieces long is the puzzle?
