Answer: Oriana was not correct, because she didn't line up the decimal points of the numbers [tex]9.298[/tex] and [tex]3.01[/tex]
Step-by-step explanation:
By definition, the "Difference" is the result of a subtraction.
In order to subtract the decimal numbers [tex]9.298[/tex] and [tex]3.01.[/tex], Oriana needed to apply these steps:
1. Write one number under the other. The decimal points must be lined up:
[tex]9.298 \\3.01-\\..........[/tex]
2. Since the decimal numbers must have the same number of decimal places, she needed to add zeros to the right side:
[tex]9.298 \\3.010-\\..........[/tex]
3. Subtract the numbers and put the decimal point in the result:
[tex]9.298 \\3.010-\\..........\\6.288[/tex]
Oriana was not correct, because she didn't line up the decimal points. Her procedure was:
[tex]9.298 \\ 0\ 3.01-\\..........\\8.997[/tex]
