Answer:
4 scoops
Step-by-step explanation:
We have to obtain 5 1/2 cups of oatmeal, that is: 2.5 cups
we only have two measures: 1/2= (0.5) and 3/4 =(0.75)
We're going to use the larger scoops first, we can notices if we use 2 scoops of 3/4 we obtain:
now if we add 2 scoops of 1/2 that is 1 cup, so, two scoops of 3/4 and two scoops of 1/2 is 2.5 cups = 5 1/2 cups
this is the minimum, if you try with three scoops of 3/4 you will obtain 2.25 cups and if you add a scoop of 1/2 you will obtain more than the measure needed. If you try only with 1/2 cup scoop, you will need 5 scoops
(a^3/b^7)^2
Bring the power of 2 into the numerator and denominator.
a^6/b^14
D gas to be sic lol idk though
