There are several different ways to write expanded form. One of them just separates the digits:
2.07 = 2 + .07
Another way to write expanded form shows the place value of each digit:
2.07 = 2*1 + 0*0.1 + 7*0.01
Yet another way to write expanded form makes use of exponents to show the place value of each digit.
2.07 = 2*100 + 0*10-1 + 7*10-22.07 in word form is two and seven hundredths.
2.07 = 2 + .07
