Here are the step-by-step solutions for each subtraction problem. To solve these, line up the decimal points and subtract just like whole numbers.
1.
4.27 - 2.62
* Subtract the hundredths: $7 - 2 = 5$
* Subtract the tenths: You can't do $2 - 6$, so borrow from the ones place. The 4 becomes a 3, and the 2 becomes 12. Now, $12 - 6 = 6$.
* Subtract the ones: $3 - 2 = 1$.
* Result:
1.65
2.
7.36 - 5.91
* Subtract the hundredths: $6 - 1 = 5$
* Subtract the tenths: Borrow from the 7 (which becomes 6). The 3 becomes 13. $13 - 9 = 4$.
* Subtract the ones: $6 - 5 = 1$.
* Result:
1.45
3.
8.03 - 4.28
* Subtract the hundredths: Borrow from the tenths, but it's a 0, so borrow from the ones (8 becomes 7). The 0 becomes 10, then lend to the 3 (which becomes 13). $13 - 8 = 5$.
* Subtract the tenths: The 0 became a 9 after lending. $9 - 2 = 7$.
* Subtract the ones: $7 - 4 = 3$.
* Result:
3.75
4.
5.25 - 1.44
* Subtract the hundredths: $5 - 4 = 1$
* Subtract the tenths: Borrow from the 5 (becomes 4). The 2 becomes 12. $12 - 4 = 8$.
* Subtract the ones: $4 - 1 = 3$.
* Result:
3.81
5.
9.89 - 3.51
* Subtract the hundredths: $9 - 1 = 8$
* Subtract the tenths: $8 - 5 = 3$
* Subtract the ones: $9 - 3 = 6$
* Result:
6.38
6.
6.29 - 5.24
* Subtract the hundredths: $9 - 4 = 5$
* Subtract the tenths: $2 - 2 = 0$
* Subtract the ones: $6 - 5 = 1$
* Result:
1.05
7.
6.44 - 2.83
* Subtract the hundredths: $4 - 3 = 1$
* Subtract the tenths: Borrow from the 6 (becomes 5). The 4 becomes 14. $14 - 8 = 6$.
* Subtract the ones: $5 - 2 = 3$.
* Result:
3.61
8.
8.16 - 5.27
* Subtract the hundredths: Borrow from the tenths, but it's a 1. Borrow from the 8 (becomes 7). The 1 becomes 11, then lends to the 6 (which becomes 16). $16 - 7 = 9$.
* Subtract the tenths: The 1 became a 0. Borrow from the 7 (becomes 6). The 0 becomes 10. $10 - 2 = 8$.
* Subtract the ones: $6 - 5 = 1$.
* Result:
2.89
9.
6.29 - 3.82
* Subtract the hundredths: $9 - 2 = 7$
* Subtract the tenths: Borrow from the 6 (becomes 5). The 2 becomes 12. $12 - 8 = 4$.
* Subtract the ones: $5 - 3 = 2$.
* Result:
2.47
