Answer:

The percentage of robins is 21%

Step-by-step explanation:

I. When sparrow is 41.5%, blackbird is 3/8 and robin is x,

Find robin by

Total percentage = sparrows + blackbirds + robins

II. Convert blackbird to percentage by

3/8 = x/100 => {means 8 is 100%}

300 = 8x

x = 37.5%

III. Find robins by

100% = 41.5% + 37.5% + x

100 = 79 + x

x = 21%

That makes robins is 21%.

Hope that help :)
