Solve the problem by using addition, subtraction, multiplication, or division. First use front end rounding to estimate the answer. Then find the exact answer. The foggiest place in a certain country is City A. It is foggy there an average of 256days each year. How many days is it not foggy each year? Find the estimated and the exact number of days.

The estimated days in a year when it is not foggy = 110 days

The exact days in a year when it is not foggy = 109 days

Step-by-step explanation:

Solve the problem by using addition, subtraction, multiplication, or division. First use front end rounding to estimate the answer. Then find the exact answer. The foggiest place in a certain country is City A. How many days is it not foggy each year?

The number of days in a year = 365 days

It is foggy there an average of 256days each year.

Find the estimated number of days when it is not foggy =

We round up the numbers

365 days to the nearest tens

= 370 days

256 days to the nearest tens

= 260 days

Hence:370 - 260 days

= 110 days

The exact number of days when it is not foggy =

= 365 − 256

= 109

step-by-step explanation:

because there are always 10 numbers in a phone number.
