Answer:

6 17/20

Step-by-step explanation:

Change the two mixed number into improper fractions

9[tex]\frac{1}{4}[/tex] = [tex]\frac{37}{4}[/tex]

2[tex]\frac{2}{5}[/tex] = [tex]\frac{12}{5}[/tex]

So the equation becomes

= [tex]\frac{37}{4}[/tex] -  [tex]\frac{12}{5}[/tex]

Now, make the two denominators the same, by multiplying 4 by 5 making the denominator 20. Remember: whatever you do to the denominator you must do to the numerator.

= [tex]\frac{185}{20} - \frac{48}{20}[/tex]

Subtract the two numerators.

[tex]\frac{185-48}{20}[/tex] = [tex]\frac{137}{20}[/tex]

Concert the improper fraction to a mixed number and you get:

[tex]6\frac{17}{20}[/tex]
