Final answer:
Rounding to the nearest tenth or hundredth involves looking at the digit immediately after the place value we want to round to, and then rounding up if it's 5 or greater, or down if it's less than 5. We followed this procedure for all given numbers.
Step-by-step explanation:
When we round to the nearest tenth or nearest hundredth, we are looking at the digit immediately after the place value we want to round to. If this digit is 5 or greater, we round up. If it's less than 5, we round down.
Here are the rounded numbers following these rules:
2.642 rounded to the nearest tenth is 2.6.
29.10 rounded to the nearest tenth is 29.1.
2,492 rounded to the nearest tenth is 2,492.0 (since there are no decimal places).
3.44 rounded to the nearest tenth is 3.4.
5,239 rounded to the nearest tenth is 5,239.0 (since there are no decimal places).
89.43 rounded to the nearest tenth is 89.4.
Rounding to the nearest hundredth is similar:
23.987 rounds up to 23.99.
3,7096 is a misprint - it should likely be formatted with a decimal point; without it, we cannot round to the nearest hundredth.
4,449 remains 4,449.00 (since there are no decimal places).
44.043 rounds down to 44.04.
999.474 rounds down to 999.47.
7.44430 rounds up to 7.44.
Always remember to look at the next digit after your rounding point to determine if you should round up or down.
