Solve for I E/I=R

$\frac{E}{I} = R$

Find the LCD of the terms in the equation.

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

$I, 1$

The LCM of one and any expression is the expression.

$I$

Multiply each term in $\frac{E}{I} = R$ by $I$ to eliminate the fractions.

Multiply each term in $\frac{E}{I} = R$ by $I$ .

$\frac{E}{I} I = R I$

Simplify the left side.

Cancel the common factor of $I$ .

Cancel the common factor.

$\frac{E}{I} I = R I$

Rewrite the expression.

$E = R I$

Solve the equation.

Rewrite the equation as $R I = E$ .

$R I = E$

Divide each term in $R I = E$ by $R$ and simplify.

Divide each term in $R I = E$ by $R$ .

$\frac{R I}{R} = \frac{E}{R}$

Simplify the left side.

Cancel the common factor of $R$ .

Cancel the common factor.

$\frac{R I}{R} = \frac{E}{R}$

Divide $I$ by $1$ .

$I = \frac{E}{R}$
