Diketahui : p 3/4,q = 5/6,r = 7/9 tentukan hasil dari 2p - q + r

p = 3/4
q = 5/5
r = 7/9
maka
2p - q + r
= 2(3/4) - 5/6 + 7/9
= 6/4 - 5/6 + 7/9
= 18/12 - 10/12 + 7/9
= 8/12 + 7/9
= 24/36 + 28/36
= 52/36
= 13/9
=1 4/9 :)

2p-q+r
2 (¾) - 5/6 + 7/9
6/4 - 5/6 + 7/9
Samakan penyebutnya
6/4 - 5/6 + 7/9
54/36 - 30/36 + 28/36
54 - 30 + 28 / 36
24+28/36
52/36
13/9
