Lula wants to round 76.24491 to the nearest hundredth. She first rounds 76.24491
to 76.245 and then rounds 76.245 to 76.25 and claims that this is the final answer.
What is wrong with this approach?

She rounded a rounded number, not allowed.
That would make 4.4445 round up to 4.45, which is not true. 
First, look at the hundredths place and the number just after it.
76.244
The 4 in the thousandths place is less than 5 so 
76.244 = 76.24
