Answer:
The Chad's friend picked [tex]2\frac{3}{8}[/tex] pounds.
Step-by-step explanation:
First the equation to find the pounds picked by Chad´s friend (x):
[tex]2\frac{1}{2} +1\frac{3}{8} +x=5\frac{1}{4}[/tex]
To solve the problem we have to put all the fractions with the same denominator (8) and reorganize the equation:
[tex]x=5\frac{2}{8} -2\frac{4}{8} -1\frac{3}{8}[/tex]
Now when can do the operations of sum and subtraction:
[tex]x=2\frac{3}{8}[/tex]
The Chad's friend picked [tex]2\frac{3}{8}[/tex] pounds.
