The product of 2 numbers is 72. The 1st number is 8 times bigger than the 2nd number. What are the missing numbers?
--------------
8 times bigger = 9 times as big
x*y = 72
y = 9x
----
x*9x = 72
9x%5E2+=+72
x%5E2+=+8
x+=+sqrt%288%29
y+=+9sqrt%288%29
--------------------
x+=+-sqrt%288%29
y+=+-9sqrt%288%29
----------------------------------------
1 times bigger = 100% increase = 2 times as big
etc.
8 times bigger is not the same as 8 times as big
