Hey there!
21 apples were rotten and got thrown out. The remaining apples were divided equally among 11 people
Ill try to answer your question
You would need one because you arent yet to 20 so it takes one tenth for example;
1.7 or 7/10
Thats my guess tho man if it is more complicated than that, SORRRYYYY
3x195=585 Hope this helped! :)
Hector = 2s or h/2
Sister = s
Equation: h/2 = s
Substitution: (20)/2 = s
10 = s
Hector’s sister found 10 seashells.
