Question

Johnny played 31/2 video games in an hour.How many could be play in 40 minutes ?

Answer 1

Answer:

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

Explanation:

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.
