| Scheme | Marks |
|---|---|
| 1 400 000 ÷ 125 000 oe or 14 ÷ 125 000 or 14 × 1000 × 100 (= 1 400 000) or 125 000 ÷ 1000 ÷ 100 (= 1.25) | M1 |
| 11.2 | A1 |
| (2) |
Notes
M1: for a first step; can be implied by an answer with digits 112
| Scheme | Marks |
|---|---|
| (4.8 × 1000 × 100) ÷ 19.2 oe or 4.8 ÷ (19.2 ÷ 1000 ÷ 100) oe | M1 |
| 25 000 | A1 |
| (2) |
Notes
M1: for division by 19.2; can be implied by an answer with digits 25
