Answer:
.19
Step-by-step explanation:
19 divided by 100 in decimal form would be .19 because 1 is in the tenths place and 9 is in the ones, when you move the nine back one you get 1.9 but you don't stop there because that's 19 divided by 10, not 100. So you go back another number making it .19 and that would be 19 divided by 100. So your answer is .19
