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 numberdid Hans start counting from? Draw a diagram or act it out.



Answer :

Its the problem where we can use diagram.
So take the look
300+10+10+10+10+10+10+10+10+10+10=300+10*10=400
There was 10 steps 
Now we can just add 10 Hans's steps to 400
400+10*100=1400 (times 100 because Hans counted back by hundreds)
The answer is 1400.
