Question

Evaluate the expression when P=2/3

3/4p - 2p

​

Answer 1

0.825 which would be like 8/10

Answer 2

-5/6

Explanation:

This is because we can substitute p for 2/3.

(3/4 x 2/3) - (2/1 x 2/3)

This shall equal:

6/12 - 4/3

In order to subtract, we need the same denominator meaning we need that three on 4/3 to be 12. So multiply 4/3 and 4/4

Equation shall be like this:

6/12 - 16/12

Now subtract keep the denominator the same!

-10/12

Simply/reduce (divide by 2/2)

-5/6!!
