Answer:
Johnny could play [tex]2\frac{1}{3}[/tex] video games in 40 minutes.
Explanation:
Given:
Johnny played video games in an hour
= [tex]3\frac{1}{2}[/tex]
To Find:
Video games Jonny can play in 40 minutes
=?
Solution:
number of videos games Jonny can play in 1 hour = [tex]3 \frac{1}{2}[/tex]= [tex]\frac{7}{2}[/tex]
And as 1 hour = 60 minutes ,
So number of videos games Jonny can play in 60 minutes =[tex]\frac{7}{2}[/tex]
=> Videos games Jonny can play in 1 minute =[tex]{\frac{\frac{7}{2}}{60}[/tex]
=>[tex]\frac{7}{20\times 6}[/tex]
=> [tex]\frac{7}{120}[/tex]
=> 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 = [tex]40 \times \frac{7}{120}[/tex]
=> [tex]\frac{7}{3}[/tex]=[tex]2\frac{1}{3}[/tex]
Hence Johnny could play [tex]2\frac{1}{3}[/tex] video games in 40 minutes.
