4 0

Answer:

24

Step-by-step explanation:

That would be:

(3/8)(30)

---------------

(15/16)(1/2)

This can be reduced in various ways.  First, divide that 30 by 15, obtaining:

   6/8

-----------

   1/32

Now invert the divisor (1/32) and multiply:

(6/8)(32/1)

This reduces to 6*4, or 24.

Ann [662]

Answer:

The salary of Doctor = $193,000

The salary of Receptionist = $34,000

Step-by-step explanation:

Given as,

Together ,the Doctor salary and the Receptionist salary = $ 227,000 per year

And the salary of Receptionist = The Doctor salary -$159,000 per year

Let the salary of Doctor = x

So, the Receptionist salary = x - $159,000 per year

And x + Receptionist salary = $ 227,000 per year

       x + x - $159,000 per year = $ 227,000 per year

Or,   2x = $ 386,000 per year

Or,     x = $ \frac{386000}{2}

Or,     x = $ 193,000

And the salary of Receptionist = $193,000 - $159,000 = $34,000

Hence,  The salary of Doctor = $193,000

And,       The salary of Receptionist = $34,000
