Answer:


(11)/(20)

Explanation:

20 is a like factor for the denominators so we can convert the fractions


(5*5)/(4*5) =(25)/(20) \\\\(7*2)/(10*2) =(14)/(20)

Now we can subtract by subtracting the numerators but keeping the denominators the same


(25)/(20) -(14)/(20) =(11)/(20)

Hope this helps lmk if you have questions
