Explanation:
Take it like this
when you put a zero on the 9, you move the digit to the left by one
48.78 divided by 9 = 487.8 divided by 90 = 4878 divided by 900
hopefully this help :)
900 is 100 times 9. So if 9 groups of 5.42 equal 48.78, then 900 groups of 5.42 equal 100 times 48.78, which is 4,878.
