To find the answer, first, find a common denominator for 11/16 and 4/10.
10 and 16 both go into 80 evenly. So, convert each fraction so that their denominators are 80.
11 x 5 = 55
---------------
16 x 5 =80
11/16=55/80
4 x 8 = 32
-----------------
10 x 8 = 80
32/80=4/10
Now you can add 4/10 and 11/16
55 + 32 = 87
4/10 + 11/16 =87/80
Finally, subtract 87/80 and 3/4
3/4= 60/80
87/60=27
87/80-3/4=27/80
11/16+4/10-3/4=27/80
27/80 = .3375
Your answer would be 27/80 in fraction form or it would be 0.3375 in decimal form
