Solve 7.2/12=1/9/x

$$\frac{ 7.2 }{ 12 } = \frac{ \frac{ 1 }{ 9 } }{ x }$$

Solve for x

$$x=\frac{5}{27}\approx 0.185185185$$

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 12x, the least common multiple of 12,x.

$$x\times 7.2=12\times \frac{1}{9}$$

Multiply 12 and \frac{1}{9} to get \frac{12}{9}.

$$x\times 7.2=\frac{12}{9}$$

Reduce the fraction \frac{12}{9} to lowest terms by extracting and canceling out 3.

$$x\times 7.2=\frac{4}{3}$$

Divide both sides by 7.2.

$$x=\frac{\frac{4}{3}}{7.2}$$

Express \frac{\frac{4}{3}}{7.2} as a single fraction.

$$x=\frac{4}{3\times 7.2}$$

Multiply 3 and 7.2 to get 21.6.

$$x=\frac{4}{21.6}$$

Expand \frac{4}{21.6} by multiplying both numerator and the denominator by 10.

$$x=\frac{40}{216}$$

Reduce the fraction \frac{40}{216} to lowest terms by extracting and canceling out 8.

$$x=\frac{5}{27}$$
