Answer:
[tex]8\frac{19}{20}[/tex] in.
Step-by-step explanation:
To find your answer, subtract.
[tex]12\frac{3}{4}[/tex] may be rewritten as [tex]\frac{51}{4}[/tex] and [tex]3\frac{4}{5}[/tex] may be rewritten as [tex]\frac{19}{5}[/tex]
Establish a common denominator, which would be the lowest common multiple of 4 and 5, which is 20. Multiply both parts of your first fraction by 5 to get a denominator of 20, and both parts of your second fraction by 4 to get a denominator of 20.
[tex]\frac{51}{4} *\frac{5}{5} =\frac{255}{20}[/tex]
and
[tex]\frac{19}{5} *\frac{4}{4} =\frac{76}{20}[/tex]
Subtract.
[tex]\frac{255}{20} -\frac{76}{20} =\frac{179}{20}[/tex]
This fraction may be rewritten as [tex]8\frac{19}{20}[/tex].
