Just you need to multiply both variables
- Multiply 5 and 9 we will get our required solution


A for the first because there are 4 aces and 1 nine of hearts. that makes it 5 cards of the 52 in a deck
d for the second because there are two cards: the queen of heart and and ace of diamond out of the 52
hope this helped :)
This is how I solved it.
2.5 multiplied by 3 is 7.5, which equals how many she takes a day.
Then I multiplied 7.5 by 10 = 75. I did that because the meds are taken for 10 days.
Also if you added 7.5 ten times is also 75.
So my final answer is that 75 tablets have been taken in total.
25/6 converts to 4 1/6 so
4 1/6 x 2 = 8 1/3
8 1/3 is your answer :)
