Solve and find the value of x. \frac{2}{3}=\frac{1.2}{x}

Question:

Solve and find the value of {eq}x. {/eq}

{eq}\displaystyle \frac{2}{3} = \frac{1.2}{x} {/eq}

Cross multiplication:

Cross multiplication is one of the mathematical technique that is used to find the values of variables. Cross multiplication is generally used to solve the problems that are related to proportion.

The expression for the given proportion is,

{eq}\dfrac{2}{3} = \dfrac{{1.2}}{x} {/eq}

Solve the expression for the value of x with the help of cross multiplication.

{eq}\begin{align*} x &= \dfrac{3}{2} \times 1.2\\ &= \dfrac{{3.6}}{2}\\ &= 1.8 \end{align*} {/eq}

Thus, the value for x is {eq}1.8 {/eq}.
