Jika A:B=2:3danB:C=5:8.Maka A:C

A:C = 2:8


semoga membantu

[tex] \frac{a}{b} = \frac{2}{3} \\ \frac{b}{c} = \frac{5}{8} \\ \frac{a}{b} = \frac{(2 \times 5)}{(3 \times 5)} = \frac{10}{15} \\ \frac{b}{c} = \frac{(5 \times 3)}{(8 \times 3)} = \frac{15}{24} \\ \frac{a}{c} = \frac{10}{24} = \frac{5}{12} [/tex]
b nya disamakan dulu
