Carlita saw 5 times as many robins as cardinals while bird watching. She saw a total of 25 birds.

How many more robins did she see than cardinals?

Carlita was either sipping the hot chocolate while she was out, or else approximating the numbers. The exact number she reported is not possible. To see why, I'll do it strictly by the math:
Robins = 5 times Cardinals = 1 time
Total birds = 6 times
6 times = 25 birds
Divide each side by 6 : 1 time = 25/6 = 4-1/6 birds
Robins = 5 times = 20-5/6 of them Cardinals = 1 time = 4-1/6 of them
Total: (20-5/6) + (4-1/6) = 25 birds.
How many more robins than cardinals = (20-5/6) - (4-1/6) = 16-2/3 more.
The math works out fine. But if the numbers she reported are true, then some of what she saw was partial birds ... legs, or feathers, things like that. Eeeew. I don't want to talk about it.

20 because 5x5=25 so she saw 5 x as many if you divide 5 and 25 you get five

Carlita saw approximately 16 more robins than cardinals based on the calculations. If we assume whole numbers, she likely saw 20 robins and 4 cardinals. The difference is approximately 16, but when considering full bird counts, it’s nearly 17 more robins than cardinals.
