4-2 equals 2
White flour makes up 2 / (2+3) of the total 10 cups: 2/5 of the total 10 cups.
2/5 times 10 is 4 cups.
You'll need 4 cups white flour and 6 cups whole wheat flour, making a total of 10 cups of flour.
You are using the distributive property so you will multiply all the numbers in the parentheses by 5. So the end expression would be 30m+20n-15p
