Which equation correctly shows the multiplication of the means and extremes in the proportion 7.2∕9.6 = 21.6∕28.8?

7.2 × 28.8 = 9. 6 × 21.6

Step-by-step explanation:

Given the equation:

7.2∕9.6 = 21.6∕28.8

The equation which provides the multiplication of the means and the extremes in the equation provided above can be obtained through cross multiplication of the two ratios or proportion.

(7.2 / 9.6) = (21.6 / 28.8)

L. H. S = R. H. S

(numerator of L. H. S * denominator of R. H. S) = (denominator of L. H. S * numerator of R. H. S)

Hence, we have ;

7.2 × 28.8 = 9. 6 × 21.6
