If a/b = 4/3 and b/c = 2/3, what is a,b, and c?
kaheart [24]

Answer:

.

Step-by-step explanation:

\frac{a}{b}  =  \frac{4}{3}

\frac{b}{c}  =  \frac{2}{3}

to give b from both equation the same value

\frac{a}{b}  =  \frac{4}{3}  \times   \frac{2}{2}  =  \frac{8}{6}

\frac{b}{c}  =  \frac{2}{3}  \times  \frac{3}{3}  =  \frac{6}{9}

a:b:c = 8:6:9

a = 8

b = 6

c = 9
