The ratio of the number of male lions to female lions in the animal reserve is 21: 20 if there are 123 lions in the animal reserve how many of the lions are female?

ANSWER: 60 female lions

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).

20/41 = x/123

Cross multiply and solve

20(123)=41x

2460=41x

60=x

it is contrapositive

total amount of money that he should pay if he has not used his duty free exemption is $98
