Answer :
Answer:
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
[tex]\frac{22}{100}[/tex] × x = 11
[tex]\frac{22x}{100}[/tex] = 11
Multiply both-side of the equation by 100
[tex]\frac{22x}{100}[/tex] × 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
[tex]\frac{22x}{22}[/tex] = [tex]\frac{1100}{22}[/tex]
(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
