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.
Remember that x/4 and 1/4*x is the same thing.
1/4*52 is therefore the same as 52/4. Fractions represent division, so 52 divided by 4 is also correct.
0.25*x is the same as 1/4*x because 1/4=0.25
4% of 52 is incorrect because the decimal form of 4% is 0.04, which is not the same as 0.25
Final answer: B
The answer is 50 because if u add 20 and 50 it makes 70:)
