Solve C/R=5/4

$$\frac { C } { R } = \frac { 5 } { 4 }$$

Solve for C

$$C=\frac{5R}{4}$$

$$R\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 4R, the least common multiple of R,4.

$$4C=5R$$

Divide both sides by 4.

$$\frac{4C}{4}=\frac{5R}{4}$$

Dividing by 4 undoes the multiplication by 4.

$$C=\frac{5R}{4}$$

Solve for R

$$R=\frac{4C}{5}$$

$$C\neq 0$$

Steps for Solving Linear Equation

Variable R cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4R, the least common multiple of R,4.

$$4C=5R$$

Swap sides so that all variable terms are on the left hand side.

$$5R=4C$$

Divide both sides by 5.

$$\frac{5R}{5}=\frac{4C}{5}$$

Dividing by 5 undoes the multiplication by 5.

$$R=\frac{4C}{5}$$

Variable R cannot be equal to 0.

$$R=\frac{4C}{5}\text{, }R\neq 0$$
