Ratio Math Question

Question

Suppose a certain population of birds has a ratio of 95 males to 210 females. If the current population of birds is 10,000 and every male bird mates with one female bird, how many female birds will be without mates.

Answer 1

95+210=305

 

95/305 = 0.31147541 = 31.147541% of the birds are male

 

So there are 3114 male birds in the population of 10000.

They will mate with 3114 female birds.

That accounts for 6228 of the 10000 birds.

So 10000 - 6228 = 3772 female birds without mates
