Solve 4/x=1.8

$$\frac { 4 } { x } = 1.8$$

Solve for x

$$x = \frac{20}{9} = 2\frac{2}{9} \approx 2.222222222$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.

$$4=1.8x$$

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

$$1.8x=4$$

Divide both sides by 1.8.

$$x=\frac{4}{1.8}$$

Expand \frac{4}{1.8} by multiplying both numerator and the denominator by 10.

$$x=\frac{40}{18}$$

Reduce the fraction \frac{40}{18} to lowest terms by extracting and canceling out 2.

$$x=\frac{20}{9}$$
