Alex sorts his collections of 85 rocks into piles of 9 rocks each? how many group of 9 rocks can alex make

Nine piles with 4 rocks left over or 9.4(repeating) piles

To figure out we'll have to divide

85/9=9 4/9

he can make 9 full piles of rocks and one that only has 4 rocks

I hope I've helped!

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
