Answer
Find out the how much fluid do i have to drink .
To prove
As given
[tex]I\ need\ to\ drink\ 8\frac{2}{4}\ cups\ of\ water\ and\ 2\frac{1}{5}\ cups\ of\ milk\ every\ day.[/tex]
I.e
[tex]I\ need\ to\ drink\ \frac{34}{4}\ cups\ of\ water\ and\ \frac{11}{5}\ cups\ of\ milk\ every\ day.[/tex]
Thus
[tex]Total\ fluid\ i\ have\ to\ drink = \frac{34}{4} +\frac{11}{5}[/tex]
L.C.M of (4,5) = 20
[tex]Total\ fluid\ i\ have\ to\ drink = \frac{34\times 5+11\times 4}{20}[/tex]
[tex]Total\ fluid\ i\ have\ to\ drink = \frac{170+44}{20}[/tex]
[tex]Total\ fluid\ i\ have\ to\ drink = \frac{214}{20}[/tex]
Simplify the above
[tex]Total\ fluid\ i\ have\ to\ drink = \frac{107}{10}[/tex]
[tex]Therefore\ the\ total\ fulid\ i\ have\ to\ drink\ is\ \frac{107}{10}[/tex] .
In the decimal form
Therefore the total fulid i have to drink is 10.7 .
