1.
Choice one
Three dozen equals thirty six cookies 12x3=36
You need 720 cookies 360x2=720
That is equivalent to sixty dozen cookies 720÷12=60
So you need twenty sets of three dozen cookies 60÷3=20
Three dozen cookie recipe
1 1/6 cups of butter
5/8 cup of white sugar
1 3/4 teaspoons of vanilla extract

Work- For each fraction I multiplied it by 20 and then divided the numerator of my answer by the
denominator to make my answer into a mixed number.
1 1/6x20=70/3 70÷3=23.3 23 1/3
5/8x20=25/2 25÷3=12.5 12 1/2
1 3/4x20=35 35
1 7/8x20=75/2 75÷2=37.5 37 1/2
5/6x20=50/3 50÷3=16.6 16 2/3
7/12x20=35/3 35÷3=11.6 11 2/3
