Essential Understanding
Dividing rational numbers is similar to dividing integers. The sign of the quotient depends on the signs of the dividend and divisor.
Standards7.NS.A.2b Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisors) is a rational number. If p and q are integers, then
–(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real-world contexts. 7.NS.A.2c Apply properties of operations as strategies to multiply and divide rational numbers. bers. |
