Answer 1

1) 3.6-8.7=3.6+(-8.7)= -5.1
2)16.8-(-2.6)=16.8+2.6=19.4
3) 0-7.6=0+(-7.6)= -7.6
4)-17.9-10.1= -17.9+(-10.1)=-28
5)-4.8-(-14.13)= -4.8+14.13=9.33
6) 0-(-16.2)= 0+16.2= 16.2

1) 3,6 - 8,7: To subtract 8.7 from 3.6, we can subtract the whole numbers and then subtract the decimal parts separately.

- Subtracting the whole numbers: 3 - 8 = -5. - Subtracting the decimal parts: 0.6 - 0.7 = -0.1.

Therefore, 3.6 - 8.7 = -5.1.

2) 16,8 - (-2,6): To subtract a negative number, we can change the sign of the negative number and then perform addition.

- Changing the sign of -2.6: -(-2.6) = 2.6. - Adding 2.6 to 16.8: 16.8 + 2.6 = 19.4.

Therefore, 16.8 - (-2.6) = 19.4.

3) 0 - 7,6: To subtract 7.6 from 0, we can subtract the whole numbers and then subtract the decimal parts separately.

- Subtracting the whole numbers: 0 - 7 = -7. - Subtracting the decimal parts: 0 - 0.6 = -0.6.

Therefore, 0 - 7.6 = -7.6.

4) -17,9 - 10,1: To subtract 10.1 from -17.9, we can subtract the whole numbers and then subtract the decimal parts separately.

- Subtracting the whole numbers: -17 - 10 = -27. - Subtracting the decimal parts: 0.9 - 0.1 = 0.8.

Therefore, -17.9 - 10.1 = -27.8.

5) -4,8 - (-14,13): To subtract a negative number, we can change the sign of the negative number and then perform addition.

- Changing the sign of -14.13: -(-14.13) = 14.13. - Adding 14.13 to -4.8: -4.8 + 14.13 = 9.33.

Therefore, -4.8 - (-14.13) = 9.33.

6) 0 - (-16,2): To subtract a negative number, we can change the sign of the negative number and then perform addition.

- Changing the sign of -16.2: -(-16.2) = 16.2. - Adding 16.2 to 0: 0 + 16.2 = 16.2.

Therefore, 0 - (-16.2) = 16.2.
