Question

The ratio of alls weight to bobs weight is 4:5, the ratio of bobs weight to lunas weight is 6:7, what is the ratio of alls weight to lunas weight?

Answer 1

All's =a
Bob's =b
Lunar =l

A:B = 4:5 B:C = 6:7
Multiply the two ratios above by 6 and 5 respectively

A:B = 24:30 and B:L=30:35
Now that we have the B's to be the same

Alls:Lunar = 24:35
