Use the tiles to complete the fraction strip model to show how you found your answer. The fractions may be used more than once or not at all.

Answer 1

1/4 + 1/3 = 7/12 of kids onjungle gym or playing kickball

Answer 2

Number of students on the jungle gym =1/4

Number of students on the playground not of jungle gym =
`1-(1)/(4)` =
`(4-1)/(4)`=
`(3)/(4)`

Number of students playing kick ball =1/3

Number of students on the playground not of playing kick ball =
`1-(1)/(3)` =
`(3-1)/(3)`=
`(2)/(3)`

Number of students on the playground is on the jungle gym or playing kickball = 1/4 +1/3

=
`(1)/(4)+(1)/(3)`=
`(3+4)/(12)`=
`(7)/(12)`
