Answer:
6 3/20
Step-by-step explanation:
We have to find the Least Common Denominator.
Sooo..
[tex]\frac{3}{4} and \frac{2}{5}[/tex]
The LCD is 20
because you can multiply 4*5 = 20 and 5*4= 20
Now turn the mixed numbers into improper fractions.
[tex]\frac{11}{4} and \frac{17}{5}[/tex]
To get the same denominator do this.
[tex](\frac{5}{5}) \frac{11}{4} + (\frac{4}{4})\frac{17}{5} \\\\\frac{55}{20} + \frac{68}{20} \\\\\frac{123}{20} \\\\6\frac{3}{20}[/tex]
Hope this helps ya! Keep smiling!
