To solve this problem you will need to use the cross product method:

1/16 of an hour → write 1 card

3/4 of an hour → write X cards


(3/4) ÷ (1/16) = X


0.75 ÷ 0.0625 = X


12 = X


Joey can write 12 Thank you cards in 3/4 of an hour.


There you go! I really hope this helped, if there's anything just let me know! :)

Answer:

12 cards

Step-by-step explanation:

Divide 3/4 hr by 1/16 hour per card:

12/16 hr divided by 1/16 hr per card is equivalent to (12/16 hr)(16/1 card/hr),

or 12 cards.  Joey can write 12 cards in 3/4 hr.
