Question

Junior's brother is 5 1/2 feet tall. Junior is 3/5 of his brother's height. How tall is Junior?

Answer 1

You have to do 5 1/2 times 3/5


`5(1)/(2) * (3)/(5) = (11)/(2) * (3)/(5) = (11*3)/(2*5) = (33)/(10) =3 (3)/(10) \ \textless \ -answer`

Answer 2

Junior is
`3 (3)/(10)\ feet` talls .

Explanation:

As given

`Junior's\ brother\ is\ 5 (1)/(2)\ feet\ tall.`

i.e

`Junior's\ brother\ is\ (11)/(2)\ feet\ tall.`

`Junior\ is\ (3)/(5)\ of\ his\ brother's\ height.`

Thus

`Junior\ heights = (3)/(5)* Junior\ brothers\ heights`

Putting all the values in the formula

`Junior\ heights = (3)/(5)* (11)/(2)`

`Junior\ heights = (33)/(10)`

`Junior\ heights = 3 (3)/(10)\ feet`

Therefore Junior is
`3 (3)/(10)\ feet` talls .
