lowest common denominator (LCD) is 3 x 2 x 2 x 8 x 3 = 96 x 3 = 288
96/288 + 216/288 + 45/288 + 256/288 = (96+216+45+256)/288 = 613/288
None of the given choices.

You can’t add them as fractions because neither 8/9 nor 1/3 will divide equally into 32. So:
1/3= 0.33333
3/4=0.75000
5/32=0.88888
8/9=0.15625
gives you a total of 2.12846, or rounded to nearest 100th=2.13 (the 8 is over 5 , so you round UP).

Neither. You figure it out 2 different ways. If you add them up finding the least common denominator you get 613/288=2.1284722
Or you can get the decimal values of each fraction and add them up which =2.1284721
