How many pints of flour should be used with 3 pints of milk in a recipe which call for 2 part of milk and 3 parts of flour?
a. 2
b. 3
c. 4 1/2
d. 5
e. 6
please answer and expalin
Cross multiply this ratio and solve for x.
2/3 = 3/x
To determine the number of pints of flour needed, we need to find the ratio between the milk and flour in the recipe and then adjust it accordingly with the given amount of milk.
The recipe states that the ratio of milk to flour is 2 parts milk to 3 parts flour. This means that for every 2 pints of milk, 3 pints of flour are required.
Given that we have 3 pints of milk, we can set up a proportion:
2 pints of milk / 3 pints of flour = 3 pints of milk / x pints of flour
To solve for x (the unknown number of pints of flour), we can cross-multiply:
2 pints of milk * x pints of flour = 3 pints of milk * 3 pints of flour
2x = 9
Dividing both sides of the equation by 2, we find:
x = 4.5
Therefore, the correct answer is option c. 4 1/2 pints of flour should be used.
Explanation: To solve this problem, we used the concept of ratio and proportion. We set up a proportion and solved for the unknown using cross-multiplication.
