I'm not sure how to solve this problem using unit rate.
Jonathan is baking several boxes of bread. He used 9cups of water to 12 cups of flour. How much water was used per cup of flour?
Ans:
9cups water/12cups flour = 3/4 cups water
--is the problem solved by acutally dividing 9 by 12 or solve by simplfying fraction of 9/12 (using 3 as common factor)?
12 cups of flour ----> 9 cups of water
1 cup of flour = 9/12 cups of water
= 3/4 cup of water
thanks!!
To solve this problem using unit rate, you can divide the amount of water by the amount of flour.
In this case, you have 9 cups of water and 12 cups of flour. So, you would divide 9 by 12 to get the unit rate.
9 cups of water / 12 cups of flour = 0.75 cups of water per cup of flour
Alternatively, you can simplify the fraction 9/12 by finding the greatest common factor (in this case, it is 3) that divides both the numerator and denominator. So, you can divide 9 by 3 and 12 by 3.
9/3 = 3
12/3 = 4
Therefore, the simplified fraction is 3/4. This means that for every 1 cup of flour, you need 3/4 cups of water.
