Question

A:B=1/2:3/8,B:C=1/2:5/9 and C:D=6/6:3/4,then the ratio A:B:C:D

Answer 1

Step-by-step explanation:

A:B=1/2×8/3=4:3

B:C=1/2×9/5=9/10

C:D=6/6×4/3=8:6

NOW

A:B=4:3, C:B=10:9

A:B=4/3×3/3=12/9

C:B=10/9

A=12,B=9,C=10

NOW

C:D=8:6

10:D=8:6

6×10=8×d

60=8d

60/8=d

15/2=d

Therefore

a=12

b=9

c=10

d= 15/2

a:b:c:d=12:9:10:15/2
