In a zoo there are 2 lions to every 5 monkeys. How many lions are there if the zoo has 45 monkeys?

Sagot :

since the ratio of lions to monkeys is given as 2:5 and you are given that there are 45 monkeys, then you'll have the number of lions as:
let 'x' be the number of lions for 45 monkeys
[tex] \frac{2}{5} = \frac{x}{45} [/tex]
[tex]5x = 45(2)[/tex]
[tex]5x = 90[/tex]
[tex]x = 18[/tex]
therefore there are 18 lions
Divide the 45 to 5 then the result will be multiply to 2

45/5 = 9

9 * 2 = 18 :)
