```AN EQUATION THAT STATES TWO RATIOS ARE EQUAL IS CALLED A PROPORTION. THE NUMBERS A AND D ARE CALLED THE EXTREMES. NUMBERS B AND C ARE CALLED THE MEANS. TO SOLVE A PROPORTION YOU TAKE THE PRODUCT OF THE EXTREMES AND SET IT EQUAL TO THE PRODUCT OF THE MEANS. 1

THE GEOMETRIC MEANS OF TWO POSITIVE NUMBERS A AND B IS THE POSITIVE NUMBER X THAT SATISFIES SO, X2 = AB AND X = √AB.
IN OTHER WORDS, TO FIND THE GEOMETRIC MEAN OF TWO POSITIVE NUMBERS MULTIPLY THE NUMBERS AND THEN TAKE THE SQUARE ROOT THE PRODUCT.
FIND THE GEOMETRIC MEAN OF 45 AND 5.
