8 1/2  -  5 2/3  =

= 17/2 − 17/3

= ((17 × 3) − (17 × 2)) / (2 × 3)

= (51 - 34) / 6

= 17/6

= 17/6

= 2 5/6

Hope this helps. :)

Answer:

[tex]2\frac{5}{6}\ cups[/tex]

Step-by-step explanation:

To find out how many cups of flour Keith has left

Subtract [tex]5\frac{2}{3}[/tex] cups from  [tex]8\frac{1}{2}[/tex] cups

Convert to an improper fractions first

[tex]5\frac{2}{3}=5+\frac{2}{3}=\frac{5*3+2}{3}=\frac{17}{3}[/tex]

[tex]8\frac{1}{2}=8+\frac{1}{2}=\frac{8*2+1}{2}=\frac{17}{2}[/tex]

so

[tex]\frac{17}{2}-\frac{17}{3}=\frac{17*3-17*2}{6}=\frac{17}{6}\ cups[/tex]

convert to mixed number

[tex]\frac{17}{6}=\frac{12}{6}+\frac{5}{6}=2+\frac{5}{6}=2\frac{5}{6}\ cups[/tex]
