A survey of students at a university shows that 3out of 4 drinks coffee. of the students who drink coffee, 1 out of 5 add cream
Snezhnost [94]

Answer:

1200

Step-by-step explanation:

The number who drink coffee is 3/4 of 8000, so ...

... (3/4)×8000 = 6000.

Of those, 1/5 add cream, so the number of coffee drinkers who add cream to their coffee is ...

... (1/5)×6000 = 1200.

_____

<em>Alternate solutions</em>

We have computed ...

... (1/5)×((3/4)×8000) = 1200

Since multiplication is associative, you can multiply the fractions first, if you wish:

... ((1/5)×(3/4))×8000 = (3/20)×8000

... = 24000/20 = 1200

or

... = 3×(8000/20) = 3×400 = 1200
