In the ratio there are 21 male lions and 20 female lions, in total 41 lions. Create a proportion relating the total number of lions in the ratio (41) and in the problem (123), and the number of female lions in the ratio (20) and in the problem (unknown).
I knew that 6 bigger than 50 is 56 and if the number is multiplied by 7 then you just do 56 divided by 7 and you get 8. So the number is 8 hope this helps :))
