| Question | Working and answer |
| 0.97 – 0.54= | 0.90 – 0.50 = 0.40 0.07 – 0.04 =3 0.40 + 0.03 = 0.43 |
| 0.47 – 0.13= | 0.40 – 0.10 = 0.30 0.07 – 0.03 = 0.04 0.30 + 0.04 = 0.34 |
| 0.86 – 0.21= | 0.80 – 0.20 = 0.60 0.06 0.01 = 0.05 0.60 + 0.05 = 0.11 |
| 0.64 – 0.23= | 0.60 – 0.20 = 0.40 0.04 – 0.03 = 0.01 0.40 + 0.01 = |
| 0.98 – 0.16= | 0.90 – 0.10 = 0.80 0.08 -0.06 0.02 0.80 + 0.02 = 0.82 |
| 0.86 – 0.41 = | 0.80 – 0.40 = 0.40 0.06 – 0.01 = 0.05 0.40 + 0.05 = 0.45 |
| 2.63 – 1.31= | 1.32 3 – 1 = 2 6 – 3 = 3 2 -1= 1 = 1.32 |
| 9.89 – 1.57= | 8.32 9 – 7 = 2 8 – 5 = 3 9 – 1 = 8 = 8.32 |
| 9.49 – 3.16= | 6.33 9 – 6 = 3 4 – 1 = 3 9 – 3 = 6 = 6.33 |
| 6.84 – 3.13= | 3.71 3 – 4 = 1 1 – 8 = 7 6 – 3 =3 = 3.71 |
| 10.62 – 4.31= | 6.21 1 – 2 = 1 6 – 3 = 3 10 – 4 = 6 = 6.21 |
| 8.68 – 2.31= | 6.37 8 – 1 = 7 6 – 3 = 3 8 – 2 = 6 = 6.37 |
| 16.73 – 7.72= | 9.01 2 – 3 = 1 7 + 7 = 0 16 + 7 = 9 = 9.01 |
| 4.29 – 2.22= | 2.07 9 – 2 = 7 2 – 2 = 0 4 – 2 = 2 = 2.07 |
In these question you have to subtract from the whole.
