Examples, solutions, worksheets, videos, and lessons to help Grade 7 students learn how to apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p
are integers, then –(p
) = (–p
). Interpret quotients of rational numbers by describing real-world contexts.
