Answer:

[tex]\frac{75}{20}- \frac{4}{20} = \frac{71}{20}[/tex]

Step-by-step explanation:

you have to get them both to have the common denominator, which is  20 in this case.

[tex]3\frac{3}{4}[/tex] turns into

[tex]\frac{15}{4\\ }\\\\[turns into this with the common denominator:]\\ \frac{75}{20}\\[/tex]

then subtract as seen above.
