Question

A school requires 2 computers for every 5 students. Write a proportion that gives the number c of computers needed for 145 students

Answer 1

The proportion would go as follows:

2   C
5 = 145      Its hard to type that but 2 would go over the 5 and an equals sign would be in the middle, then C over 45. To solve then take 145 times 2 and divide it by 5.
Hope this helps.
