the ratio of robins to blackbirds that visit our feeder is 4 to 7. If there are a total of 132 birds,how many robins visit the feeder?

May 12th, 2015

The number of robins that visited the feeder is given  by the value of the ratio  that  represents robins divided by the total ratio times the total number of the birds.

The total ratio is 11; 4 +7

The total number of birds  is 132,

The value of the ratio  that  represents robins is  4

So  you will have  4/11 x 132, which is 48 robins.

Hope this helps! Please best me if it does or ask any question if you are not satisfied!
