This answer is 1.1.
It is because:
5 goes into 5.5 ... 1.1 time. You would divide each 5 by 5 and then put the decimal in the middle.
On a model it would be something like this, 5 sections of 100 and 10 combined together.
Take a closer look!
Draw 6 100 by 100 graphs,
Color in 5 and 50 hundredths of the models.
Divide the colored sections by 1 and 10 hundredths.
Key:
The models are the 6 squares.
The 5.5 is the color red
The black is the division of 1.1
Hope this helps:
