Answer:
350 Students are in the choir altogether.
Step-by-step explanation:
Divide 70 in half to get 35, or 10% of the students.
Multiply 35 by 10 to get 350, or 100% of the choir. (AKA a lot of students for one choir director to keep track of!)
If anyone has anything else to add that I missed, feel free!
Hope this helps, also :)
