Answer: [tex]2\frac{1}{8}\ pounds[/tex] pounds are left for his grandmother .
Step-by-step explanation:
Since we have given that
Quantity of apple he picked is given by
[tex]6\frac{1}{2}\\\\=\frac{13}{2}\ pounds[/tex]
Quantity of apples he picked to his aunt is given by
[tex]2\frac{3}{4}\\\\=\frac{11}{4}\ pounds[/tex]
Quantity of apples he picked to his mother is given by
[tex]1\frac{5}{8}\\\\=\frac{13}{8}\ pounds[/tex]
So, total quantity left for his grandmother is given by
[tex]\frac{13}{2}-(\frac{11}{4}+\frac{13}{8})\\\\=\frac{13}{2}-\(\frac{22+13}{8}\\\\=\frac{13}{2}-\f\rac{35}{8}\\\\=\frac{13}{2}-\frac{35}{8}\\\\=\frac{52-35}{8}\\\\=\frac{17}{8}\\\\=2\frac{1}{8}\ pounds[/tex]
Hence, [tex]2\frac{1}{8}\ pounds[/tex] pounds are left for his grandmother .
