Answer:
[tex]\huge\boxed{\bf\: \frac{93}{20}=4.65}[/tex]
Step-by-step explanation:
[tex]3 \frac { 1 } { 4 } + 1 \frac { 2 } { 5 }[/tex]
Now,
[tex]3 \frac { 1 } { 4 } \\= \frac{4 * 3+1}{4}\\= \frac{13}{4}[/tex]
Then,
[tex]1 \frac { 2 } { 5 }\\= \frac{1* 5+2}{5} \\= \frac{7}{5}[/tex]
So,
[tex]3 \frac { 1 } { 4 } + 1 \frac { 2 } { 5 }\\= \frac{13}{4}+\frac{7}{5}\\ \\\mathrm{LCM = 20}\\\\= \frac{65}{20}+\frac{28}{20} \\=\boxed{\bf\: \frac{93}{20}=4.65}[/tex]
