QuestionSolve for $x$ in the equation $\frac{30}{100}=\frac{x}{18}$ .

Studdy Solution

STEP 1

Assumptions1. We have a proportion equation $\frac{30}{100}=\frac{x}{18}$ . We need to solve for $x$ .

STEP 2

A proportion is an equation that states that two ratios are equal. In this case, we have $\frac{30}{100}$ (which can be simplified to0.) and $\frac{x}{18}$ . We can solve for $x$ by cross multiplying.

STEP 3

Cross multiply the two fractions.
$30 \times18 =100 \times x$

STEP 4

implify the left side of the equation.
$540 =100 \times x$

STEP 5

To isolate $x$ , divide both sides of the equation by100.
$\frac{540}{100} = x$

STEP 6

Calculate the value of $x$ .
$x = \frac{540}{100} =5.4$ The solution is $x =5.4$ .

Studdy Solution

STEP 1

Assumptions1. We have a proportion equation 30100=x18\frac{30}{100}=\frac{x}{18}10030​=18x​ . We need to solve for xxx.

STEP 2

A proportion is an equation that states that two ratios are equal. In this case, we have 30100\frac{30}{100}10030​ (which can be simplified to0.) and x18\frac{x}{18}18x​. We can solve for xxx by cross multiplying.

STEP 3

Cross multiply the two fractions.30×18=100×x30 \times18 =100 \times x30×18=100×x

STEP 4

implify the left side of the equation.540=100×x540 =100 \times x540=100×x

STEP 5

To isolate xxx, divide both sides of the equation by100.540100=x\frac{540}{100} = x100540​=x

STEP 6

Calculate the value of xxx.x=540100=5.4x = \frac{540}{100} =5.4x=100540​=5.4The solution is x=5.4x =5.4x=5.4.
