Question

Round each number to the place of the underline digit 80,547.645 the 4 in 645 is underlined

Answer 1

To round the number 80,547.645 to the place of the underlined digit (which is the 4 in 645), you'll want to look at the digit immediately to the right of it, which is 5.

Since the digit after the underlined digit (4) is 5 (which is 5 or greater), you round up the 4 to 5.

Thus, rounding 80,547.645 to the place of the underlined digit gives you 80,547.65.
