c.

p=-1/5

q=-3/10

r=2/5

Answer:

  • a) 1 1/6
  • c) 1/2

Step-by-step explanation:

<u>The expression given:</u>

  • p - q + r

<u>Evaluate for each case:</u>

a)

<u>p = 2/3, 1 = -1/3, r = 1/6</u>

  • p - q + r =
  • 2/3 - (-1/3) + 1/6 =
  • 2/3 + 1/3 + 1/6  =
  • 1 + 1/6 =
  • 1 1/6

c)

<u>p = 1/-5, q = -3/10, r = 2/5</u>

  • p - q + r =
  • -1/5 - (-3/10) + 2/5 =
  • -2/10 + 3/10 + 4/10 =
  • 5/10 =
  • 1/2
