4. After all the values are the way you want, press . 
• This displays the solution (value of X). Pressing  again will return to 
the Coefficient Editor. 
Important: A Math ERROR will occur if you perform a calculation while 0 
is input for a coefficient. 
Changing the Ratio Expression Type 
Re-enter the RATIO Mode and select the ratio expression type you want 
from the menu that appears. Changing the ratio expression type causes the 
values of all Coefficient Editor coefficients to change to zero. 
RATIO Mode Calculation Examples 
   To calculate X in the ratio 1 : 2 = X : 10 
  (RATIO) 
  (a:b=X:d) 1  2  10  
   
 
  To calculate X in the ratio 1 : 2 = 10 : X 
  (RATIO) 
  (a:b=c:X) 1  2  10
