Question

Last year there were 221 students and 13 teachers at Hillard School. This year there are 272 students. The principal wants to keep the same student-to-teacher ratio as last year. Which proportion can the principal use to find x, the number of teachers needed this year? StartFraction 272 over 221 EndFraction = StartFraction 13 over x EndFraction StartFraction 221 over 272 EndFraction = StartFraction x over 13 EndFraction StartFraction 221 over 13 EndFraction = StartFraction 272 over x EndFraction StartFraction 13 over 221 EndFraction = StartFraction 272 over x EndFraction

Answer 1

see explanation

Explanation:

Using proportion to find the teachers required x, then

`(221)/(272)` =
`(13)/(x)` ( cross- multiply )

221x = 3536 ( divide both sides by 221 )

x = 16

The number of teachers required this year is 16
