A school district needs 3 teachers for every 70 children. They expect to have 14,700 children in the district next year. At this time, they have 612 teachers. How many more teachers are needed

First we set up a proportion to find how many teachers are needed. We solve that by cross multiplying We get that there will be 630 teachers needed. Since they have 612 teachers, we subtract to find out how many more teachers are needed: 630 teachers needed -612 teachers already ---------------------- 18 more teachers. Edwin
