Question

Charlie has 5 times as many stamps as ryan.They have 2,160 stamps in all.How many stamps does ryan have

Answer 1

Ryan has 360 stamps

let Ryan have x stamps , then Charlie has 5x ( 5 times as many )

the toal stamps combined is 2160, hence

x + 5x = 2160

6x = 2160 ( divide both sides by 6 )

x =
`(2160)/(6)` = 360

Ryan has 360 stamps and Charlie has ( 5 × 360 ) = 1800 stamps

Answer 2

Let x be the number of stamps Charlie has and y be the number of stamps Ryan has.


`2160 = x + y \\ \\ x = 5y`
Then you can replace the x in the first equation and get

`2160 = 5y + y \\ 2160 = 6y \\ y = 2160 / 6 \\ y = 360`
Ryan has 360 stamps
