Question

Answer 1

a: b= 5: 3
b: c= 3: 2
a: b: c
5: 3
3: 2
5: 3: 3
3: 3: 2
15: 9: 6
5: 3: 2

Answer 2

here you go ☆☆

▪$3a = 5b \\ a= \frac{5b}{3}$

similarly

▪$4b = 6c \\ c = \frac{4b}{6}$

a:c =>

▪$\frac{ \frac{5b}{3} }{ \frac{4b}{6} } \\ \frac{5b}{3} \times \frac{6}{?4b}$

▪$\frac{5}{2}$

□so a:c => 5:2
