Have another percents question..just not clicking on how to set up equation.

Question

26 is what percent of 40?

Answer 1

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

Answer 2

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%

 

 

Answer 3

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.

26/40 = x/100

crossmultiply......26*100=40*x

divide both sides by 40.....(26*100)/40=40x/40

65 =x

           so 65/100 = .65 or 65%

             

Answer 4

26/40=13/20=(13)(5)/(20)(5)=65/100=65 %

Answer 5

Just take as X percent .

 

  Write an expression for x percent of 40 as 40X

 

  let that equals 26 and solve for X.
