Hi Kristin,
 
26 is what percent of 40
 
is means =
 
of means multiply
 
percent means 1/100
 
26=(y/100) × 40
 
26=y×40/100
 
26×100=y×40
 
2600=y×40
 
2600/40=y×40/40
 
65=y
 
26 is 65 percent of 40
Hi Kristin;
40x=26
x=26/40
Multiply numerator (top) and denominator (bottom) by 2.5...
x=[(26)(2.5)]/[(40)(2.5)]
x=65/100
x=65%
 
 
26/40 = x/100     set up as a ratio and proportion type equation.  26 is to 40 as x is to 100.
            why 100?  because 100 is the basis for percent.  
                          solve the equation for x and we get 65.
                          so 65/100 = .65 or 65%
