Sandra is making cookies that require 5 1/2 cups of oatmeal. she has only two measuring cups: a one-half cup and a three-fourths cup. what is the smallest number of scoops that she could make in order to get 5 172 cups?

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

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
