Divide Decimals and Estimate the Answer
We can estimate the answers by first rounding both decimals to the nearest whole numbers and then finding the difference between them.
45.7 - 16.4 can be estimated by rounding each number to the nearest whole numbers 46 and 16.
46 - 16 = 30
45.78 - 19.67 can be estimated by round to the nearest whole numbers 46 and 20.
46 - 20 = 26
Now, let's put this method into practice!
