The question is missing some parts. Here is the complete question.

Mrs. Smith is making homemade silly putty for hte children in her class. Here is how the ingredients are mixed:

1/5 of the mixture is starch

1/2 of the mixture is glue

1/5 of the mixture is water

1/10 of the mixture is borax

When theingredients are mixed in the same ratio as shwon above, every batch of silly putty will be the same consistency. Study hte measurements for each batch in the table. Fill in the blanks so that every batch will have the same consistency.

Mrs. Smith wants to mix a 15-cup batch of the mixture for Mr. Brown's class. How many cups of each ingredient should she use in the mixture?

________ cups starch

________ cups glue

________ cups water

________ cups borax

Answer: 3 cups of starch;

              7.5 cups of glue;

              3 cups of water;

              1.5 cups of borax

Step-by-step explanation: The ratio to create the same consistency for the silly putty is  1/5:1/2:1/5:1/10, which means that for the whole mixture one fifth is starch; half is glue; another one fifth is water and one tenth is borax.

For a batch of 15 cups:

Starch = 1/5.15

Starch = 3

Glue = 1/2.15

Glue = 7.5

Water = 1/5.15

Water = 3

Borax = 1/10.15

Borax = 1.5

In other words, to create a 15-cup batch of silly putty with the same consistency described above, Mrs. Smith will have to mix 3 cups of atrach, 7.5 cups of glue, 3 cups of water and 1.5 cups of borax.
