Answer:
6.21 times more
Step-by-step explanation:
Assuming 2.04 x 10^11 was only a typo
you would need to first equal the powers of 10
so 20.4 x 10^10 and 3.28 x 10^10
now that they have the same powers

if it's asking for how many times i would approximate it to 6.21 times more
The mistake is line 4, she should have divided 42 by 5, not add 5 and 16
