Complete the table below.
We can start by looking at the first
line. We’re given a number 581. And then we move to the right one
box and we see that we now have 580. The second box has followed the
instructions to take the number 581 and subtract one. Moving over another box, we see
that the instructions were to take the number and subtract 10: 581 minus 10 equals
571. The last box tells us that we need
to take the number and subtract 100: 581 minus 100 equals 481.
It’s our job to follow the same
procedure with the number 425: 425 minus one equals 424. We’ve taken a one away from the
ones place: five minus one equals four. And we haven’t changed the place
value of the hundredth or the tenth: 425 minus one equals 424. The next box represents 425 minus
10. The number 425 has a two in the
tenth place. And we want to take one 10 away
from that: 425 minus 10 equals 415. We’ve taken a one, one 10, away
from the two tens for an answer of 415. Our final box wants to know where
425 minus 100 would be. If we have four hundredths and we
take away one of those hundreds, we’ll be left with 300. 425 take away 100 equals 325.
Our boxes can be filled in with the
numbers 424, 415, and 325.
