Jordan spent 22% of his time doing math homework. If hw spent 11 minutes on his math homework. How many minutes did he spend on
devlian [24]

Answer:

The total minutes he spend on his homework are 50 minutes.

Step-by-step explanation:

<em>It is given that Jordan spent 22% of his time for homework on maths.</em>

<em>It is also given that he spent 11 minutes of time on maths homework.</em>

The above two statements are equal.

Let the total time for homework be "x".

Thus, the equation can be written as,

(\frac{22}{100})(x) = 11

x = (\frac{100}{22})(11) = 50 minutes

Thus the total minutes he spend on his homework are 50 minutes.
