Today you are to just focus on clue 3.
Clue 3 asks you to divide by 10 and 100.
When dividing by 10 your digits move one place to the right but your decimal point *altogether everyone* IT NEVER MOVES!
When dividing by 100 your digits move TWO places to the right but your decimal point *altogether everyone* IT NEVER MOVES!
I have included the place value grid below to help you. If you’re stuck, place your digits in the grid and move them to help you. You can always write the value of the digits above the numbers too, if that helps.
