To write a number in expanded form you have to take notice of the place each number is in.

That is, if the number is in the first place to the left of the decimal dot, that is a "unit", symbolized as x*1

If the number is in the second place to the left after the decimal dot, that is a "ten", symbolized as x*10

If the number is in the third place to the left of the decimal dot that is a "hundreth", symbolized as x*100

The number in the fourth place is in the "thousands", symbolized as x*1000

All numbers after the decimal dot are decimal values.

The first number to the rigth is in the "tenth" place, symbolized as x*1/10

The second place is in the "hundreths" place, symbolized as x*1/100

The thistd place is in the "thousands" place, symbolized as x*1/1000

So for the number


362.72

The first value, 3, is in the hundreths place, you can write it in expanded form as 3*100

The second value, 6, is in the tenths place, you can write it in expanded form as 6*10

The third value, 2, is in the units place, its expanded form is 2*1

Next is the decimal dot.

The first value after the decimal dot, 7, is in the tenths place, its expanded form is 7*1/10

The second value after the decimal dot, 2, is in the hundreds place, you can write it in expanded form as 2*1/100

Add all expressions to have the given number written in expanded form:


362.72=(3\cdot100)+(6\cdot10)+(2\cdot1)+(7\cdot(1)/(10))+(2\cdot(1)/(100))
