To solve: the proportions 2436=2x by cross products property.

Calculation: The product of the numerator of the ratio and of the denominator of the other is known as a cross product. Cross products can be used to determine whether the ratios form a proportion or not. If the cross products are equal, then the ratios form a proportion. 2436=2x [Write the proportion.] 24×x=36×2 [Apply cross products property.] 24x=72 [Multiply.] 24x24=7224 [Divide each side by 24 to place the variable on one side of the equation] x=3 [Simplify.] Hence, the solution of the proportions 2436=2x is x=3.

Calculation:
The product of the numerator of the ratio and of the denominator of the other is known as a cross product. Cross products can be used to determine whether the ratios form a proportion or not. If the cross products are equal, then the ratios form a proportion.

\frac{24}{36} = \frac{2}{x}

[Write the proportion.]

24 \times x = 36 \times 2

[Apply cross products property.]

24 x = 72

[Multiply.]

\frac{24 x}{24} = \frac{72}{24}

[Divide each side by 24 to place the variable on one side of the equation]

x = 3

[Simplify.]
Hence, the solution of the proportions

\frac{24}{36} = \frac{2}{x}

x = 3
