HI I NEED HELP FOR 80 POINTS There are white, blue, and red boats in a marina. Three-fourths of the boats in the marina are white, 4/7 or the reminding are blue and the rest are red if there are 9 red boats how many boats are in the marina!!!

look below

Step-by-step explanation:

( 1 / 6 ) * ( 2 / 5 ) = 1 / 15. This means that 1 / 15 of the boats in the marina are blue.

To get the fraction of the number of red boats in the marina, we can do 1 - ( 1 / 15 ) - ( 5 / 6 ).

1 - ( 1 / 15 ) - ( 5 / 6 ) = 1 / 10, so we know that 1 / 10 of the boats in the marina are red.

Now we know that there are 12 red boats in total, and red boats make up 1 / 10 of all the boats in the marina. All you have to do next is multiply 12 * 10, and you'll get the answer to how many boats are in the marina.

Good luck, and I hope this helps.

like 40 boats in the marina
