Answer: There is \(3\frac{3}{4}\ pounds\) of cheese Sam buy altogether.
Step-by-step explanation:
Since we have given that
Number of pounds of Swiss cheese is given by
\(2\frac{1}{4}\\\\=\frac{9}{4}\ pounds\)
Number of pounds of Cheddar is given by
\(1\frac{1}{2}\\\\=\frac{3}{2}\ pounds\)
Total number of pounds of cheese Sam buy altogether is given by
\(\frac{9}{4}+\frac{3}{2}\\\\=\frac{9+6}{4}\\\\=\frac{15}{4}\\\\=3\frac{3}{4}\ pounds\)
Hence, there is \(3\frac{3}{4}\ pounds\) of cheese Sam buy altogether.
