sally and Hans started counting at the same time. sally counted on by tens from 300.Hans counted back by hundreds. after six counts, they had reached the same number. What number did Hans start counting fror?
Sally:
1. 300
2. 300 + 10 = 310
3. 310 + 10 = 320
4. 320 + 10 = 330
5. 330 + 10 = 340
6. 340 + 10 = 350
Now we know that the last number of Hans was 350, so:
6. 350
5. 350 + 100 = 450
4. 450 + 100 = 550
3. 550 + 100 = 650
2. 650 + 100 = 750
1. 750 + 100 = 850
