text  Estimate the sum of  end text 14 7 over 8 text  and  end text 2 11 over 25 text  by replacing each fraction with  end text 0 comma 1 half comma text  or  end text 1 text .  end text

  1. 17
  2. 17 1 half
  3. 18
  4. 10 1 half

hintHint:

7 over 8 space i s space 0.875 space w h i c h space i s space n e a r space t o space 1 space a n d space c a n space b e space r e p l a c e d space b y space 1.
11 over 25 space i s space 0.44 space w h i c h space i s space n e a r space t o space 0.5 space a n d space c a n space b e space r e p l a c e d space b y space 1 half.
S o space t h e space r e s u l t space w i l l space b e left parenthesis 14 plus 1 right parenthesis plus left parenthesis 2 plus 1 half right parenthesis equals 17 1 half.

The correct answer is: 17 1 half


    14 7 over 8 plus 2 11 over 25 equals 15 plus 2 1 half equals 17 1 half
