How do you write 2.78 in expanded form

2+7/10 + 8/100

Or
Two point seven tenth eight hundredth

To write 2.78 in expanded form, you'll need to break down the number into its place values. Here's how you can do it:

2.78 = 2 + 0.7 + 0.08

In this expanded form, the 2 represents the number in the "ones" place, the 0.7 represents the number in the "tenths" place, and the 0.08 represents the number in the "hundredths" place.

78.2 in expanded form

2.0 + .7 + .08

If your teacher wants the answer in words, change the numbers to their names, for example, .7 would be seven tenths
