Question

I don't get number 1 please help me

Answer 1

When you are going from a larger measurement (such as meter) to a smaller measurement (such as centimeter), you will have to multiply by units of ten. Specifically if you are going from m to cm, you will use (n x 10^2) with n being the given number for meters. When you are going from a smaller measurement (such as centimeter) to a larger measurement (such as meter), you will have to divide by units of ten. Specifically if you are going from cm to m, you will use (n / 10^2) with n being the given number for centimeters.
