  1. 11
  2. 12
  3. 13
  4. 111 half

hintHint:

15 over 17 equals 0.8823 space w h i c h space c a n space b e space o u n d e d space o f f space t o space o n e
22 over 23 equals 0.95652 space w h i c h space c a n space b e space r o u n d e d space o f f space t o space o n e
S o space t h e space s o l u t i o n space w i l l space b e space left parenthesis 5 plus 1 right parenthesis plus left parenthesis 6 plus 1 right parenthesis equals 13

The correct answer is: 13


    5 15 over 17 plus 6 22 over 23 equals 6 plus 7 equals 13
