Question

Hi I need help with this pls​

Answer 1

• a) 1 1/6
• c) 1/2

Explanation:

The expression given:

• p - q + r

Evaluate for each case:

a)

p = 2/3, 1 = -1/3, r = 1/6

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

c)

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

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

Answer 2

Solution given:

a.

p=2/3

q=-1/3

r=1/6

now

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

=
`(2*2+1*2+1)/(6)=(7)/(6)`

c.

p=-1/5

q=-3/10

r=2/5

now

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

=
`(-1*2+3+2*2)/(10)=(5)/(10)=½`
