<u>Answer: </u>

Johnny could play 2\frac{1}{3} video games in 40 minutes.

<u>Explanation:</u>

Given:  

Johnny played  video games in an hour = 3\frac{1}{2}

To  Find:

Video games Jonny can play in 40 minutes =?

Solution:

number of videos games Jonny  can play in 1 hour = 3 \frac{1}{2}= \frac{7}{2}

And as 1 hour = 60 minutes ,  

So number of videos games Jonny can play in 60 minutes =\frac{7}{2}

=> Videos games Jonny can play in 1 minute ={\frac{\frac{7}{2}}{60}

=>\frac{7}{20\times 6}

=> \frac{7}{120}

=> Videos games Jonny can play in 40 minute = 40 x Videos games Jonny can play in 1 minute

=> Videos games Jonny can play in 40 minute = 40 \times \frac{7}{120}

=> \frac{7}{3}=2\frac{1}{3}

Hence Johnny could play 2\frac{1}{3} video games in 40 minutes.
