Tolong ya pleasse di kumpulin besok,sama caranya ya yg jelas

Answer 1

4 : 5 = 12 : 15
jadi umur andi = 15

5. a : b = 5 : 6 = x : 18
=(18 : 6) x 5
= 3 x 5
= 15

6. 6 : 4
selisih = 2 = 50000
6 = 15000
4 = 10000
maka uang ayah = 150.000

7. a+b =52
a : b = 6:7
a= 6/13 x 52 = 24
b= 7/13 x 52 = 28

15. 24 m : 21 m
24m : 300 = 8 cm
21m : 300 = 7 cm
jadi p dan l = 8 cm dan 7 cm
