Here is the equation:
[tex] 18 - 4 \frac{8}{9} [/tex]
Since you're subtracting a mixed number, make the whole number as a mixed number, and subtract.
[tex] 18 \rightarrow 17 \frac{9}{9} [/tex]
Your new equation is:
[tex] 17 \frac{9}{9} - 4 \frac{8}{9} [/tex]
First subtract the whole numbers:
[tex] 17-4=13 [/tex]
Now subtract the fraction:
[tex] \frac{9}{9} - \frac{8}{9} = \frac{1}{9} [/tex]
Add the whole number and fraction:
[tex] 13 + \frac{1}{9} = 13 \frac {1}{9} [/tex]
Your answer is [tex] 13 \frac{1}{9} [/tex]
