Question

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

Answer 1

Johnny could play
`2(1)/(3)` video games in 40 minutes.

Step-by-step explanation:

Given:

Johnny played video games in an hour =
`3(1)/(2)`

To Find:

Video games Jonny can play in 40 minutes =?

Solution:

number of videos games Jonny can play in 1 hour =
`3 (1)/(2)`=
`(7)/(2)`

And as 1 hour = 60 minutes ,

So number of videos games Jonny can play in 60 minutes =
`(7)/(2)`

=> Videos games Jonny can play in 1 minute =
`{((7)/(2))/(60)`

=>
`(7)/(20* 6)`

=>
`(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 * (7)/(120)`

=>
`(7)/(3)`=
`2(1)/(3)`

Hence Johnny could play
`2(1)/(3)` video games in 40 minutes.
