Answer:
98.9940 to 99
42.426 to 42
Explanation:
To start off, 5 or more, go next door (round up), so 4 or less stays the same.
To round to the nearest foot, we know that we'll have to round the ones place. So we look at the tenths place for reference:
98.9940
We have to round the 8 using the 0.8. Because 8, as a digit, is larger than 5, we have to go next door—round up:
99.0000 = 99
Same thing for 42.426:
To round to the nearest foot, we know that we'll have to round the ones place. So we look at the tenths place for reference:
42.426
We have to round the 2 using the 0.4. Because 4, as a digit, is less than 5, we stay the same:
42.000 = 42
