Quizz time III 100

This one about digits. we have nine digit : 1,2,3,4,5,6,7,8,9 arrange them to become addition of integer and fraction that always result 100. ex: 3 + (69258/714) = 100 82 + (3546/197) = 100 there are more like the example. Can you find the rest (more than eight i guess) ? You are free to use any tool.

@Sweet Emotion You are really fast, but i make this time a little bit hard. 😁 it should always be x+(y/z).

Got 4 1+2+3+5+4*6-7+8*9 = 100 (2+5+7+3*6-4+8*9)/1 =100 1+2+3-4+5+6+78+9 =100 (-2-3-4-5+6*7+8*9)/1=100 Edit: Oh wait. I spent 30 mins getting the wrong solutions? Damnit >_<

questions: 1. should it always be ( x + y / z ) or could be ( a / b + d / c ) or ( a + b + c / d ) ? 2. is / floor division or division ?

Woah man. The permutations are endless on this one. This one is not exactly x+(y/z) but it's the closest I could manage : [-2+4*3+5]+[6+7+8*9]/[1]

I have done it. Will post as soon as I get it onto mobile. Cheers. All answers have a slight tolerance of being from 99 to 101unfortunately because of int datatype. A few examples are: 93 6215 784 78 6513 294 87 6923 514

Here is the code. It won't completely run in code playground though. https://code.sololearn.com/c10BAhXfFGbP/?ref=app

Thanks. I would appreciate it a lot if you could look into where I went wrong. I was trying to replace int x with double x and 100 with 100.000 but it just gives me the same result. I cant seem to find the reason I'm not getting it. Maybe it's trivial but I'm certainly gonna lose sleep over it lol.
