Question

Jane watched one television program for 1/4 of an hour and then changed channels to watch another program for 20 min. Write an equation to describe the fraction of an hour that Jane watched television

Answer 1

Jane's TV watching =
`(1)/(4)hours + 20mins`
=
`(1)/(4)hours + (20mins)( (1hour)/(60mins))`
=
`(1)/(4)hours + (1)/(3)hours`
=
`(3)/(12)hours + (4)/(12)hours`
=
`(7)/(12)hours`
