Solve Multiplication Equations with Decimals

What is the main concept of solving multiplication equations with decimals

Isolate the variable by dividing both sides

What is the inverse of multiplication

Division

What is the definition of an equation

A math sentence with an equal sign that shows two sides are the same

What is a coefficient

The number multiplying the variable

What is the definition of an inverse operation

An operation that undoes another operation

Example solve 0.13u = 1.17

u = 9

How to check the solution for 0.13u = 1.17

Substitute u = 9 and see that 0.13 × 9 = 1.17

Example solve 0.25x = 3.5

x = 14

How to check the solution for 0.25x = 3.5

Substitute x = 14 and see that 0.25 × 14 = 3.5

What is the rule for solving multiplication equations with decimals

Divide both sides by the decimal coefficient

What should you always do after solving

Check your work by substituting the solution back into the original equation
