Answer 1

Hello Maleyja

 

Let's see what we have.

 

3 1/3 cups brown sugar

4 1/4 cups sugar

1 5/6 cups water

6 1/2 cups flour

 

Let's restate these mixed numbers as improper fractions

10/3 cups brown sugar
17/4 cups sugar
11/6 cups water
13/2 cups flour

 

So we have 10     17    11    13

                 --- + --- + --- + ---

                  3      4      6       2

 

We need to find the common denominator.

 

In this case the common denominator is 12

 

10  4     17  3     11  2    13   6
---•-- + ---•-- + ---•-- + ---•--
 3   4     4   3     6    2     2    6

 

40     51    22     26

--- + --- + --- + ---

12     12    12     12

 

139

----  = 11 7/12 cups

 12
