Estimate 16.82-8.264 by first rounding each number to the nearest tenth. pls help i need the right answer!

so the answer is about 8.40

Steps

find the number in the tenth place and look one place to the right for the rounding digit. Round up if the number is greater than or equal to 5 but since 2 is less than 5, stays the same

16.820⇒16.82

8.264⇒8.364

Remember round up if the number is greater than or equal to 5 and round down if the number is less than 5.

now that we have rounded everything. It is time to estimate 16.82-8.364.

16.82 is close to 16.80 and 8.364 is close to 8.40.

16.80-8.40=8.40

but there’s no any figure there!
