Question

It is believed that 3/4 of our dreams involve people that we know. Write an expression to describe the number of dreams that feature people you know if you have d dreams. Now use that expression you wrote to predict the number of dreams that include people you know out of 28 dreams.

Answer 1

3/4 of dreams = 3/4 of 'd'

The expression is
`(3)/(4)d`

When d = 28
Number of dreams =
`(3)/(4)(28)= (3*28)/(4)=21`

Answer: 21 dreams
