4 x 1.50 = 6

4 x ___ = 2
4 x 1/2 = 2

1/2 x 10 = 5 brownies


15: 5
3 : 1

Answer 2

Eder needs 15 cookies and 5 brownies for every 10 plates he makes.

Explanation:

In order to know hoy many cookies and brownies Eder needs for 10 plates, given the fact that he needs 6 cookies and 2 brownies for every 4 plates, we need to perform the following calculation:

6C + 2B = 4X (plates)

6/4C + 2/4B = X

1.5C + 0.5 B = X

So, as we can see, 1.5 cookies and 0.5 brownies are needed for every plate. To know how many of those are needed for ten plates, we ned to multiply those numbers by 10.

1.5 x 10 = 15

0.5 x 10 = 5

Eder needs 15 cookies and 5 brownies for every 10 plates he makes.
