Answer 1

Answer:

Please find the grid of Sparrows and Cardinals below.

Step-by-step explanation:

Ratio 3:1 of Sparrows to Cardinals

There are at least 7, but less than 11 sparrows that eat at Mrs. Sims bird feeder

Let's build the grid for sparrows and cardinals, this way:

Sparrows = 7 - 8 - 9 - 10 - 11

Cardinals = 2 - 3 - 3 - 3 - 4

For calculating the number of cardinals we use the ratio 3:1 and round the number of cardinals to the next whole number.

Number of sparrows 7 to 11

Number of cardinals 2 to 4
