Chef joe is baking cookies. He needs 4/10 of a cup of milk to make 10 cookies. What is the total amount of milk in cups that he needs to make 50 cookies?

2 Cups of milk would be needed to bake 50 cookies

Step-by-step explanation:

We can set this type of question up as a ratio. The problem states that for every 10 cookies 4/10 cups of milk is used therefore the ratio 10:4/10 can be created.

With the ratio created we have to get the 10 cookies to 50 cookies. Multiplying 10 by 5 will equal to 50, but with everything you do on one side of a ratio you need to do on the other side, therefore you need to multiply 4/10 by 5. 5*4/10 would then equate to 20/10. 20/10=2. There would be 2 cups of milk for 50 cookies.

2 cups

Step-by-step explanation:

4/10 - -> 10 cookies

x - -> 50 cookies

direct variation

10*5=50

4/10*5=2

2 cups
