und each decimal to the nearest tenth. 0.32 (2) 3.87 \( 3 \quad 0.709 \) \( \qquad \) 3.9 \( \qquad \) 12.75 512.745 645.059

Rounding decimals is like playing a game of "spot the neighbors"! To round 0.32 to the nearest tenth, you look at the hundredths place (which is a 2) and since it's less than 5, you keep the tenths place (3) as is. So, 0.32 becomes 0.3! Now, take 3.87: with 8 in the hundredths place (greater than 5), you bump up the tenths place to 9, leaving you with 3.9. For 0.709, the digit in the hundredths place is 0, so the number stays at 3.7. Finally, 12.75 turns into 12.8, 512.745 becomes 512.7, and 645.059 rounds to 645.1! Rounding can be fun when you spot those little numbers!
