A different salad dressing uses a combined total of 2.5 cup of olive oil and vinegar per batch. Consider how many cups of this salad dressing are in 4 1/2 batches Is 8 cups in 4 1/2 batches a reasonable answer? Explain how to determine the number of decimal digits in the answer without solving the problem.

There are 11.25 cups of salad dressing

Step-by-step explanation:

A different salad dressing uses a combined total of 2.5 cup of olive oil and vinegar per batch.

Hence:

1 batch = 2.5 cup of salad dressing

4.5 batches = x

Cross Multiply

1 × x = 4.5 × 2.5

x = 11.25 cups of salad dressing.

Is 8 cups in 4 1/2 batches a reasonable answer? No it is not.

Explain how to determine the number of decimal digits in the answer without solving the problem.

The decimal digits in the answer is 2 decimal places. This is because

4.5 = 1 decimal place

2.5 = 1 decimal place

Adding the decimal places together = 2 decimal places.
