Question

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 1

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"

$\frac{3}{5}$  ÷  4    =     $\frac{3}{5}$ $* \frac{1}{4}$    =      $\frac{3 * 1}{5 * 4}$     =     $\frac{3}{20}$
