Question

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 females

Answer 1

So,

The trick to solving ratio problems is to add the units together and then divide the total number of things by the total number of units.

21 + 20 = 41


`(123)/(41) = 3`

The unit value is 3 lions.

Now, multiply the unit value by the number of units for female lions (20).

3 * 20 = 60

There are 60 female lions in the reserve.

Answer 2

Answer: 60

Explanation:

Given: The ratio of the number of male lions to female lions in the animal reserve = 21:20

The total number of lions reserve=123

Let the number of male lions be 21x and the number of female lions be 20 x.

Now, According to the question, we have

`21x+20x=123\\\\\Rightarrow\ 41x=123\\\\\Rightarrow\ x=(123)/(41)\\\\\Rightarrow\ x=3`

Now, the number of female lions =
`20(3)=60`

Hence, the number of female lions = 60
