tolong bantuin wajib pakai cara

1. C/20 = 5/25 = (c x 25 ) = (20 x 5) = 25c = 100
25 c = 100
c = 100 ÷ 25 = 4

2. 18/d = 57/95 = (18 x 95) = d x 57 = 1710 = 57d
57 d = 1710
d = 1710 ÷ 57 = 30

3. 2/130 = 9/e = (2 x e ) = (130 x 9) = 2e = 1170
2e = 1170
e = 1170 ÷ 2 = 585

Ket : masing-masing d kali silang

Semoga membantu

3. (c×25)=(5×20)
25c=100
c=4

4. (18×95)=(57×d)
1710=57d
d=30

5. (2×e)=(9×130)
2e=1170
e=585
