The compounded ratio of the ratios: (a : b), (c : d), (e : f) is (ace : bdf)

sum 1:

The compunded ratio of (2:3),(6,11)and (11:2)

a=2;b=3;c=6;d=11;e=11 and f=2

here formula is:(ace:bdf)
2*6*11=132 and 3*11*2=66

then ratio is 132:66

132/66=2/1 answer is: 2:1

sum 2:
What is the equivalent compound ratio of 5:6::7:10::6:5 ?

a=5;b=6;c=7;d=10;e=6 and f=5

here formula is:(ace:bdf)
5*7*6=210 and 6*10*5=300

then ratio is 210:300

210/300=7/10(div by 30) answer is: 7:10

div using calculator answer is : 0.7
