Question 838928
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^2 = 72}}}
{{{x^2 = 8}}}
{{{x = sqrt(8)}}}
{{{y = 9sqrt(8)}}}
--------------------
{{{x = -sqrt(8)}}}
{{{y = -9sqrt(8)}}}
----------------------------------------
1 times bigger = 100% increase = 2 times as big
etc.
8 times bigger is not the same as 8 times as big
