question

Dale is making a deep-dish apple pie. He estimates that he will need 1.75 times the amount of filling he would use for a regular apple pie. If his usual apple pie recipe calls for 6 cups of apples, how many cups should Dale use for his deep-dish pie?

cups

solution

Dale uses 6 cups of apples for a regular apple pie. He estimates he will need 1.75 times that amount for a deep-dish pie. Multiply to find how many cups of apples Dale should use.

First, multiply a related set of whole numbers. Find

175

Now, count the number of decimal places in the factors. There are two decimal places in 1.75, so move the decimal point two places to the left in your answer.

1,050. → 10.50

Dale should use 10.5 cups of apples for his deep-dish pie.
