Answer 2

cost of
`3(1)/(4)` kg sugar is
`5.80`

Explanation:

Converting the quantity of sugar from mixed fraction to proper fraction

`1(1)/(4) =((1*4)+1)/(4) =(5)/(4)`

Cost of
`(5)/(4)` kg of sugar= 2.25

Cost of 1 kg of sugar
`2.25*(4)/(5) \\=0.45*4\\=1.80`

similarly,
`3(1)/(4) =((3*4)+1)/(4)=(13)/(4)`

So, the cost of
`(13)/(4)` kg of sugar is

`(13)/(4)*1.80 \\=5.80`

cost of
`3(1)/(4)` kg sugar is
`5.80`
