Answer:
1.6
Step-by-step explanation:
1. you move the decimal point from 0.9 to 9.0
2. then you move the decimal point from 1.44 to 14.4
3. you do 14.4/9
4. 9 goes into 14 one time
5. 9 times 1 equals 9
6. 14-9=5
7. move the next place value down, which is 4.
8. So 9 goes into 54 6 times
9. then the answer is 1.6 after you move the decimal point up
