a:b = 4:5
b:c=3:2
b was 5 then it was 3, so you have to find the common multiple which is 15.
you’d have to times the 4 (a) by 3 since that 5x3 is 15
you’d have to times the 2 (c) by 5 since 5x3 is 15 again.
therefore the answer would be
a:b:c
12:15:10
I hope this makes sense it was kinda hard to explain sorry :)

Hello,

Step-by-step explanation:

[tex]\frac{a}{4} = \frac{b}{5}[/tex]  and  [tex]\frac{b}{3} = \frac{c}{2}[/tex]

or 5a = 4b and 2b = 3c ⇔ 15a = 12b and 10b = 15c

In fractions :

[tex]\frac{a}{12} = \frac{b}{15}[/tex]  and [tex]\frac{b}{15} = \frac{c}{10}[/tex]

We have :

a:b:c = 12:15:10
