Question

Sam bought 2 1/4 pounds of Swiss cheese and 1 1/2 pounds of cheddar at the deli. How many pounds of cheese did Sam buy altogether?

Answer 1

Answer: There is
`3(3)/(4)\ pounds` of cheese Sam buy altogether.

Explanation:

Since we have given that

Number of pounds of Swiss cheese is given by

`2(1)/(4)\\\\=(9)/(4)\ pounds`

Number of pounds of Cheddar is given by

`1(1)/(2)\\\\=(3)/(2)\ pounds`

Total number of pounds of cheese Sam buy altogether is given by

`(9)/(4)+(3)/(2)\\\\=(9+6)/(4)\\\\=(15)/(4)\\\\=3(3)/(4)\ pounds`

Hence, there is
`3(3)/(4)\ pounds` of cheese Sam buy altogether.

Answer 2

2 1/4 + 1 1/2 = 9/4 + 3/2 = 9/4 + 6/4 = 15/4 = 3 3/4
