WRITING DECIMALS IN EXPANDED FORM

The decimal point or dot separates the whole number part to
the left of the dot, from the fractional part to the right of the dot.

If the whole number part is zero, we write a zero in front of the decimal point. So, we write
0:37 instead of :37.

Write the expanded form of each number.
