Question

I need to drink 8 2/4 cups of water and 2 1/5 cups of milk every day. How much fluid do i have to drink

Answer 1

Find out the how much fluid do i have to drink .

To prove

As given

`I\ need\ to\ drink\ 8(2)/(4)\ cups\ of\ water\ and\ 2(1)/(5)\ cups\ of\ milk\ every\ day.`

I.e

`I\ need\ to\ drink\ (34)/(4)\ cups\ of\ water\ and\ (11)/(5)\ cups\ of\ milk\ every\ day.`

Thus

`Total\ fluid\ i\ have\ to\ drink = (34)/(4) +(11)/(5)`

L.C.M of (4,5) = 20

`Total\ fluid\ i\ have\ to\ drink = (34* 5+11* 4)/(20)`

`Total\ fluid\ i\ have\ to\ drink = (170+44)/(20)`

`Total\ fluid\ i\ have\ to\ drink = (214)/(20)`

Simplify the above

`Total\ fluid\ i\ have\ to\ drink = (107)/(10)`

`Therefore\ the\ total\ fulid\ i\ have\ to\ drink\ is\ (107)/(10)` .

In the decimal form

Therefore the total fulid i have to drink is 10.7 .
