The errors are that she is just multiplying incorrectly.

10* 1.75 = 17.5
100* 1.75= 175
1000* 1.75 = 1750

When you are multiplying by tens (hundreds and thousands are also considered tens since they are just 10*10 and 10*10*10), you should just be moving the decimal place forward one place. 
This goes back to very basic math when you are learning place values.
