TOLONG DIJAWAB YAA SEMANGAT 8 SAMPE 10 YAAA yg bener semua dijawab soalnya nilainya tinngi klo salah gua report

8. 23/5 : 5/6
13/5 : 5/6
78/25
d. 3 3/25

9. K = 2(p+l)
240 = 2(7x + 5x)
240 = 24x
10 = x
lebar = 5x = 5.10 = 50(a)

2 3/5 ÷5/6 = 13/5 × 6/5 =78/25
=3 3/25 (d)
--------
K= 2(p+l)
P+l= 240/2=120
P÷l=7÷5
P=7/12 × 120=70 cm
l= 5/12 ×120=50 cm (a)
--------
1÷4.000.000
1cm mewakili 4.000.000cm=40 km
Js= 200km
Jp= 200÷40=5 cm (c)
