The total number of cupcakes ordered, using proportions, is of:
5.
<h3>What is a proportion?</h3>
A proportion is a fraction of an amount, and this fraction is combined with the unit rates in the context of a problem to find the desired amounts in the same context of the problem.
These amounts are found using basic arithmetic operations, especially multiplication and division, with the unit rates in the context of the problem.
In this problem, the amounts are given as follows:
- Family: Seven halves of cupcakes = 7/2 = 3.5 cupcakes.
- Friends: Six quarters of cupcakes = 6/4 = 1.5 cupcakes.
The total number of cupcakes that will be ordered is the sum of the amounts that will be needed for the family and for the friends, hence:
3.5 cupcakes + 1.5 cupcakes = 5 cupcakes.
<h3>Missing Information</h3>
The problem is:
I'd like to order 7 halves of cupcakes for my family plus an amount for six friends, considering that each of them wants a quarter. What is the total amount?
