Question

Estimate the sum of 1 1 over 9 and 2 8 over 9 by replacing each fraction with 0,1 half, or 1.

  1. 3
  2. 3 1 half
  3. 4
  4. 4 1 half

hintHint:

1 over 9 equals 0.1111111 space w h i c h space i s space n e a r space z e r o space a n d space c a n space b e space r o u n d e d space o f f space t o space z e r o.
8 over 9 equals 0.88888889 space w h i c h space i s space n e a r space space 1 space a n d space c a n space b e space r o u n d e d space o f f space t o space 1.
S o space w e space w i l l space w r i t e left parenthesis 1 plus 0 right parenthesis plus left parenthesis 2 plus 1 right parenthesis equals 3 plus 1 equals 4

The correct answer is: 4


    1 1 over 9 plus 2 8 over 9 equals 1 plus 3 equals 4
