Riding on a school bus are 20 students in ninth grade, 10 students in tenth grade, 9 students in eleventh grade, and 7 students in twelfth grade. Approximately what percent of students on the bus are in ninth grade?

How do I go about solving this?

1 answer

total number of students on the bus = 46
so what is the percentage equivalent of 20/46 ?
You just want an approximation.
If it had been 20/50 it would have been 40%
you the denominator is a bit less than 50, so your
percentage is a bit more than 40%,
How about 43% or 44% ?
