Hi- I'm not sure what they mean by place value. But hopefully this helps.
A: Lee needs 370 pencils and wants to buy them by the box. There are 10 in a box so we need to divide 370 by 10.
370/10= 37
So he would need to buy 37 boxes
B: A carton has 10 boxes and each box has 10 pencils so first we need to find out how many pencils are in a carton:
10*10=100
To get 370 pencils, Lee would have to buy 4 cartons totaling 400 pencils
