Angelina_Jolie [31]

Jordan spends 50 minutes on his homework.

Step-by-step explanation:

Given,

Time spent on Maths homework = 11 minutes

This represents the 22% time of his total homework.

Let,

x be the total time spent on homework.

22% of x = 11

$\frac{22}{100}*x=11\\0.22x=11$

Dividing both sides by 0.22

$\frac{0.22x}{0.22}=\frac{11}{0.22}\\x=50$

Jordan spends 50 minutes on his homework.
