Sweet T noticed the ratio of long boards to short boards was 1:4. If there were 35 surfboards at the beach, how many were short boards?

Answer 1

28 short boards

Explanation:

1:4= 1 long board and 4 short boards= 5 boards
`35/5=7` combinations of 1:4 boards

`7 xx 4 = 28` short boards and 7 long boards

`4/5 xx 35` are short

`=28` short boards.
