3/5 of your class earned an A or a B last week. 1/4 of those teammates earned an A. what fraction of you class earned an A? Possible answers could be 4/9, 7/20, 2/1, 3/20 but which one is it?

Answer :

Answer:

3/20

Step-by-step explanation:

  • 3/5 earned an A or B = "3/5 of the class"
  • 1/4 of 3/5 earned an A = "3/5 of class divided by 4"

[tex]\frac{3}{5}[/tex]  ÷  4    =     [tex]\frac{3}{5}[/tex] [tex]* \frac{1}{4}[/tex]    =      [tex]\frac{3 * 1}{5 * 4}[/tex]     =     [tex]\frac{3}{20}[/tex]
