One-step equations multiplication and division

One-step equations multiplication and division

Students will solve one-step equations using multiplication and division

Remember

• To solve a one-step equation: identify the operation in the equation, use the inverse operation on both sides to isolate the variable

• To check the equation: rewrite the original problem, substitute the value for the variable, and simplify using order of operation

Multiple Choice

What is the operation in the equation?

 $\frac{m}{8}=6$  

• multiplication

• division

• addition

• subtraction

Multiple Choice

What inverse operation must be used in order to solve the equation?

 $\frac{m}{8}=6$  

• multiplication

• division

• addition

• subtraction

Solve  $\frac{m}{8}=6$  

• The operation in the equation is division

• The inverse operation is multiplication

• To solve, multiply both sides by the denominator

• Reminder: Use parentheses to show multiplication

Solve  $\frac{m}{8}=6$  

•  $\left(8\right)\ \frac{m}{8}=6\left(8\right)$  
  

•  $m=48$ 

• Reminder: Use parentheses to show multiplication

Check  $\frac{m}{8}=6$  

• Copy original equation $\ \frac{m}{8}=6$  
  

• Substitute solution for variable  $\frac{48}{8}=6$  

• Simplify (on both sides) using order of operations  $6=6$  

• If the left and right side of the equation are equal, then your solution is correct

Multiple Choice

 $9\ =\ \frac{a}{9}$  

• a = 18

• a = 0

• a = 1

• a = 81

Multiple Choice

 $\frac{a}{6}=0$  

• a = 60

• a = 6

• a = 0

• a = 1

Multiple Choice

 $\frac{x}{2}=6$  

• x = 4

• x = 12

• x = 3

• x = 8

Multiple Choice

 $\frac{x}{5}=3$  

• x = 15

• x = 2

• x = 8

• x = 53

Solve  $7n=84$  

• The operation in the equation is multiplication

• The inverse operation is division

• To solve, divide both sides by the coefficient

• Reminder: Use fraction bar to show division

Solve  $7n=84$  

•  $\frac{7n}{7}=\frac{84}{7}$  

•  $n=12$  
  

• Reminder: Use fraction bar to show division

Check  $7n=84$  

• Copy original equation $\ 7n=84$  
  

• Substitute solution for variable (use parentheses to represent multiplication)  $7\left(12\right)=84$  

• Simplify (on both sides) using order of operations  $84=84$  

• If the left and right side of the equation are equal, then your solution is correct

Multiple Choice

27 = 9a

• a=3

• a=36

• a=18

• a=9

Multiple Choice

6y = 24

• y=18

• y=4

• y=6

• y=3
