You got 1. correct and 2. incorrect:

  1. $88.0$
  2. $75.20$

For 2., remember that you are being asked to round $75.195$ to the hundredths place, which means that you need to include the significant figure in the hundredths place.

But be careful to recognise when a $0$ is a significant figure and when it isn't: http://www.staff.vu.edu.au/mcaonline/units/numbers/numsig.html
