Subtract the decimals by aligning the decimal points. Regroup 1 tenth into 10 hundredths.<br><br>
&bull; 7.05 − 4.16<br>
&bull; 5 hundredths − 6 hundredths: not enough, regroup<br>
&bull; 7 ones 0 tenths 5 hundredths = 6 ones 10 tenths 5 hundredths<br>
&bull; 10 tenths 5 hundredths = 9 tenths 15 hundredths (since 1 tenth = 10 hundredths)<br>
&bull; Actually: 7.05 = 6 ones 9 tenths 15 hundredths<br>
&bull; 15 hundredths − 6 hundredths = 9 hundredths<br>
&bull; 9 tenths − 1 tenth = 8 tenths<br>
&bull; 6 ones − 4 ones = 2 ones<br>
&bull; 7.05 − 4.16 = 2.89<br>
&bull; Check: 2.89 + 4.16 = 7.05 ✓<br><br>
Final Answer: 2.89
