Answer:
Mrs Fishers has 20 students in her class.
Step-by-step explanation:
This problem can be written in the proportion [tex]\frac{35}{100}[/tex] = [tex]\frac{7}{x}[/tex] because [tex]\frac{35}{100}[/tex] is 35%, which is equal to [tex]\frac{7}{x}[/tex] because that is also 35%.
[tex]\frac{35}{100}[/tex] = [tex]\frac{7}{x}[/tex] --- write proportion
35x = 700 --- cross multiply (multiply x by 35 and 7 by 100)
x = 20 --- divide both sides by 35.
