Answer:
80%
Step-by-step explanation:
40/50 of the teachers in the meeting were first-year teachers.
100 is the denominator to percents when transfered into fractions so we do 100 ÷ 50 which is 2 so we multiply 50 by 2 to get to 100. This means that we must multiply 40 by 2 as well to get the numerator.
40 x 2 = 80
This equals 80/100. Like I said before, fractions with denominators of 100 can easily be transfered into percentages. It would be 80%.
