Question

stacy says the 4 in 643 has a value of 4 tens or 40 do you agree with stacy reasoning explain use picture,words or number in your answer.

Answer 1

Yes, because when you look at the number 6 is the hundreds, 4 is the tenths, and three is a regular number.  if you change the 3 to a zero and get rid of the 6 you would get 40 as your answer.
