Question

explain how you can mentally determine that 35,000 divided by 70 =500

Answer 1

35/7=5, and the 0 in 70, cancels out a 0 is 3500, so you're left with two zeros, so 5 with two zeros is 500

Answer 2

because its easy to know that 35 divided by 7 equals 5 so just cross off one zero at the end of 35000  and at the end of 70 then just add the two zeros from 35000 and you get 500

hope this helpss
