Diketahui perbandingan p:q=6:5,q:r=2:7 dan r:s= 4:3.tentukan a.perbandingan p:q:s b.nilai p+q jika diketahui =75

A. p:q=6:5
q=5p/6
q:r=2:7
5p/6 : r=2:7
r=5p/6.7 per 2
r=35p/12
r:s=4:3
35p/12 : s=4:3
s=35p/12.3/4
s=35p/16
p:q:s=p:5p/6:35p/16
Kalikan 48
48:40:105
B. s=75??
48+40 /105.75
=88/7.5
=62,86
