PROPORTION

In the concept of proportion, the statement saying that the product of the means is equal to the product of the extremes is _____?

Answer:

\large \green{ \boxed{ \purple{ \sf{A. \: true}}}}A.true

Example:

3:5=18:30 (3:5 is proportional to 18:30). The extremes are the numbers outside (3 and 30), and the means are the numbers inside (5 and 18).

\begin{gathered} { \frac{3}{5} = \frac{18}{30}} \\ {(3)(30) = (5)(18)} \\ {90 = 90}\end{gathered}53=3018(3)(30)=(5)(18)90=90

Therefor, the product of the means is equal to the product of the extremes
