Answer 1

Answer      

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

To prove

As given

$I\ need\ to\ drink\ 8\frac{2}{4}\ cups\ of\ water\ and\ 2\frac{1}{5}\ cups\ of\ milk\ every\ day.$

I.e

$I\ need\ to\ drink\ \frac{34}{4}\ cups\ of\ water\ and\ \frac{11}{5}\ cups\ of\ milk\ every\ day.$

Thus

$Total\ fluid\ i\ have\ to\ drink = \frac{34}{4} +\frac{11}{5}$

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

$Total\ fluid\ i\ have\ to\ drink = \frac{34\times 5+11\times 4}{20}$

$Total\ fluid\ i\ have\ to\ drink = \frac{170+44}{20}$

$Total\ fluid\ i\ have\ to\ drink = \frac{214}{20}$

Simplify the above

$Total\ fluid\ i\ have\ to\ drink = \frac{107}{10}$

$Therefore\ the\ total\ fulid\ i\ have\ to\ drink\ is\ \frac{107}{10}$ .

In the decimal form

Therefore the total fulid i have to drink is 10.7 .
