Hello there,

In order to substract fractions, you need to put all the fractions to the same denominator.

[tex] \frac{3}{4} -\frac{4}{13}[/tex]

[tex] =\frac{3*13}{4*13} -\frac{4*4}{13*4}[/tex]

[tex] =\frac{39}{52} -\frac{16}{52}[/tex]

[tex] =\frac{23}{52} [/tex]

So bob's your uncle, the answer would be :

[tex] =\frac{23}{52} [/tex]

Hope this helps !

im not an expert but i think i can help, first, make your fractions have the same denominator. you do this by multiplying, and remember what you do to your denominator you must do to your numerator. starting with 3/4×13=39/52 now, 4/13×4=16/52

now, you can solve 39/52-16/52, leaving you with 23/52, now normally you would simplify, but you cant simplify this one so your final answer is 23/52. hope this helps, best of luck on your work :)
