Answer 1

2 1^/4 + 11^/2 = 9^/4 + 3^/2 = 9^/4 + 6^/4 = 15^/4 = 3 3^/4

Answer 2

`(15)/(4)` pounds of cheese Sam had bought altogether.

Step-by-step explanation:

Mass of Swiss cheese bought by Sam =
`2(1)/(4)=(9)/(4) pounds`

Mass of cheddar cheese bought by Sam =
`1(1)/(2)=(3)/(2) pounds`

Total mas of cheese bought by Sam:

`(9)/(4) pounds+(3)/(2) pounds`

`=(9* 2+3* 4)/(4* 2) pounds=(30)/(8) pounds=(15)/(4) pounds`

`(15)/(4) pounds=3(3)/(4)` pounds

`(15)/(4)` pounds of cheese Sam had bought altogether.
