In your own words, describe how to estimate a product of a multiplication expression using compatible numbers. Use the example of 2.35 x 21.02 in your answer.

to find a reasonable answer you can estimate to help. You could do 2 x 21 to get a general idea of what the actual product will be.

Step-by-step explanation:

2 x 21 = 42

2.35 x 21.02 = 49.397
