Answer:
<u>1 cup</u> of milk Juan should use.
Step-by-step explanation:
Given:
A recipe calls for 120 ml of milk for each 200 g of flour.
Juan is going to use 1 pound of flour.
Now, to estimate the number of cups of milk.
Let the quantity of milk be
Now, to convert the pound of flour to gram.
1 pound = 453.59 g.
So, Juan is going to use 453.59 g of flour.
As, given recipe calls for 120 ml of milk for each 200 g of flour.
So, 120 ml is equivalent to 200 g.
Thus, is equivalent to 453.59 g.
Now, to solve by using cross multiplication method:
By cross multiplying we get:
Dividing both sides by 200 we get:
The quantity of milk = 272.154 ml.
Now, converting the quantity into cups by conversion factor:
1 ml = 0.004 cup.
So, 272.154 ml of milk is:
272.154 × 0.004
=1.088 cups.
Estimating the number = 1 cup.
Therefore, 1 cup of milk Juan should use.
