Noel has been working on making handmade birthday cards for 11/12 hour. If each card takes 1/6hour to make, how many cards did he make? choices for the answers : 1: one fith. 2: five six's. 3: five. 4: five wholes and one half.
To find the number of cards Noel made, we need to divide the total time spent by the time it takes to make one card.
Total time spent = 11/12 hour
Time to make one card = 1/6 hour
Number of cards = (Total time spent) / (Time to make one card)
Number of cards = (11/12) / (1/6)
Number of cards = (11/12) * (6/1)
Number of cards = (11/2)
Number of cards = 5.5
Since the number of cards must be a whole number, we can conclude that Noel made 5 cards.
