Pls Dijawab Dengan Cara Kerjanya Temen² Kalau Bisa Semuanya Tlong Dijawab Smua Tmen

p=4
q=3
r=(pq) / (p+2q)
=(4.3) / (4+2(3))
=12 / 10

(p-q) /r
=>(4-3) / 12/10
=>1 / 12/10
=>10/12 (A)

Diketahui :
p = 4.
q = 3.
r = pq/(p + 2q).

Ditanya :
(p - q)/r?

Jawab :
r = pq/(p + 2q).
r = (4)(3)/(4 + 2(3)).
r = 12/(4 + 6).
r = 12/10.

= (p - q)/r.
= (4 - 3)/12/10.
= 1/12/10.
= 1 × 10/12.
= 10/12. (A)
