4.76 rounded to one decimal place is 4.8~
First you make the fractions top heavy instead of mixed numbers, so:
5/2 × 16/5
Then you just multiply across:
5 × 16 = 80
2 × 5 = 10
Your answer is 80/10, which can be simplified to 8.
Do the opposite of what you did in reverse order.
so add 100 and divide by 2 in that order.
(80 + 100)/2
