Answer 1

heya here's ur answer .........
a:b=15/2:5(multiply both with 5/4)
b:c=5/4:3(multiply both with 5)
then u will get .......
a:b=15/8:25/4
b:c=25/4:15
15/8:25/4:15=a:b:c

Answer 2

Let a= 15/2 x and b = 5x for the ratio a:b
And for the ratio b:c ; b= 5/4y and c = 3y

For the values of b to be same 5x = 5/4 y
or y=4x

So c= 3y = 12x
Now a:b:c = 15/2:5:12
