Solve real-world and mathematical problems involving the four operations with rational numbers

What you'll learn

1. Select the appropriate operation(s) — addition, subtraction, multiplication, or division — for a given real-world problem involving rational numbers
2. Apply all four operations fluently to integers, fractions, and decimals, including negative values
3. Solve multistep real-world problems by sequencing multiple operations with rational numbers
4. Interpret the sign and magnitude of an answer in context, checking whether the result is reasonable
5. Convert between fractions, decimals, and mixed numbers as needed to perform operations efficiently

Prerequisites

• Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers
• Apply and extend previous understandings of multiplication and division to multiply and divide rational numbers
