Answer:
10) Exact Answer: 36
Estimate: 36
11) Exact Answer: 2001
Estimate: 1900
Step-by-step explanation:
10a) To find the exact answer, simply divide the given numbers.
10b) To find the estimated answer, use compatible numbers. We know that any "hundred" number is easily divisible by 5. Therefore, 900/5 = 36.
It is possible for the estimate to be the same as the exact answer.
10a) To find the exact answer, simply divide the given numbers.
10b) To find the estimated answer, use compatible numbers. There is no pattern we can look for, so round to the nearest whole number.
We know that if we rounded .38 to 0 or 1, the answer would not be nearly as close as if we rounded .38 to .4.
Therefore, 760/.4 = 1900
