Solve RM3=20%

$$R M 3 = 20 \%$$

Solve for M_3

$$M_{3}=\frac{1}{5R}$$

$$R\neq 0$$

Steps for Solving Linear Equation

Reduce the fraction \frac{20}{100} to lowest terms by extracting and canceling out 20.

$$RM_{3}=\frac{1}{5}$$

Divide both sides by R.

$$\frac{RM_{3}}{R}=\frac{\frac{1}{5}}{R}$$

Dividing by R undoes the multiplication by R.

$$M_{3}=\frac{\frac{1}{5}}{R}$$

Divide \frac{1}{5} by R.

$$M_{3}=\frac{1}{5R}$$

Solve for R

$$R=\frac{1}{5M_{3}}$$

$$M_{3}\neq 0$$

Steps for Solving Linear Equation

Reduce the fraction \frac{20}{100} to lowest terms by extracting and canceling out 20.

$$RM_{3}=\frac{1}{5}$$

The equation is in standard form.

$$M_{3}R=\frac{1}{5}$$

Divide both sides by M_{3}.

$$\frac{M_{3}R}{M_{3}}=\frac{\frac{1}{5}}{M_{3}}$$

Dividing by M_{3} undoes the multiplication by M_{3}.

$$R=\frac{\frac{1}{5}}{M_{3}}$$

Divide \frac{1}{5} by M_{3}.

$$R=\frac{1}{5M_{3}}$$
