Example Question #1 : Multiply And Divide Rational Numbers Using Properties Of Operations: Ccss.Math.Content.7.Ns.A.2c
Let's work from left to right since it's only multiplication and division. Since there is only one negative number, the product of is negative which is
. Now we have
. Two negative numbers in a division problem makes the answer positive.
Example Question #2 : Multiply And Divide Rational Numbers Using Properties Of Operations: Ccss.Math.Content.7.Ns.A.2c
Solve:
When solving this problem remember our orders of operation, or PEMDAS.
PEMDAS stands for parentheses, exponents, multiplication/division, and addition/subtraction. When you have a problem with several different operations, you need to solve the problem in this order and you work from left to right for multiplication/division and addition/subtraction.
Simplify the quantities inside the parentheses. Then multiply and distribute the coefficient in front.
