Sal spent 22% of his time doing math. if he spent 11 minutes on his math homework, how many minutes spent on his homework?

Therefore, Sal spent 50 minutes on his homework

Step-by-step explanation:

Let x be the total number of minutes Sal spent in doing his homework

22% of x  = 11 minutes

 ×   x   =  11

 = 11

Multiply both-side of the equation by 100

  ×  100  = 11×100

On the left-hand side of the equation 100 will cancel-out 100

Our equation becomes;

22x  = 1100

Divide both-side of the equation by 22 to get the value of x

 =  

(On the left-hand side of the equation 22 at the numerator will cancel-out 22 at the denominator leaving us with just x while on the right-hand side of the equation 1100 will be divided by 22)

x = 50 minutes

Therefore, Sal spent 50 minutes on his homework
