Ninths means you have something divided into 9 pieces. So how many equal one whole? All 9 pieces! But you don't have one whole, you really have eight. So if 9 pieces are in one whole, ____ x 1 = 8? Multiply this number by the 9 pieces in each whole one and you'll have your answer!

There are nine parts of the whole to form ninths. Therefore: 9 x 8 = 72 (72/9 seventy-two over nine).

81 of them because 81/9 = 9
54 of them because 54/9 = 6
You can make 4 wholes from 8 halves.
(1/9)*x=3 x=3*(9/1) x=27
