Question

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

Answer 1

The total fluid you have to drink is 10 7/10 = 10.7 cups.

Explanation:

The daily requirement of water = 8 2/4 cups

Now,
`8 (2)/(4)  = 8+  (2)/(4)  = 8+ 0.5 = 8.5`

or, the daily water requirement = 8.5 cups

The daily requirement of milk = 2 1/5 cups

Now,
`2 (1)/(5)  = 2+  (1)/(5)  = 2+ 0.2 = 2.2`

or, the daily milk requirement = 2.2 cups

So, The total fluid needed = Cups of (Water + Milk) needed

= 8.5 cups + 2.2 cups

= 10.7 cups

Also,
`10.7 = 10 + 0.7 = 10 + (7)/(10)  = 10(7)/(10)`

Hence, the total fluid you have to drink is 10 7/10 cups.
