Tentukan bilangan yang tidak diketahui. a. 27/84 = 18/□ b. 2/5 = □/20 c. 70/□ = 7/15 d. □/15 = 52/60 e. 56/72 = □/18 f. 35/84 = 5/□

a.
b.2/5 = 4/20 → 2/4 = 1/4, 5/20 = 1/4 (perbandingan)
c.70/150 = 7/15 → 70/7 = 10, 150/15 = 10
d.13/15 = 52/60 → 13/52 = 1/4, 15/60 = 1/4
e.56/72 = 14/18 → 56/14 = 4/1, 72/18 =1/4
f.35/84 = 5/12 → 35/5 = 7, 84/12 = 7
