4:35For hver 1 brun hund er der 2 blank hunde.
BLANK is wrong. It sould be "sort".
Thanks you Khan academy. I learn so many things.

Personally, this part is wrong. The actual answer ratio is. 18:9. How do I know?

There are 8 big fish in the picture, so we can count the total fish to finish the first ratio. To complete the second ratio, we need to find an equivalent ratio fo the first. To make an equivalent ratio, we multiply both values in the first ratio by the same number. We can also divide both values by the same number.

The tank has a total of 18 fish, we can count to see there are 8 big fish for every 18 total fish. We want to find a ratio of big fish to total fish that is equivalent to 8:18. Since we divide by 2, to get from 8 big fish to 4 big fish, we also need to divide the number of total fish by 2.

Big fish : 8 divided by 2 = 4

Total fish : 18 divided by 2 = 9

For the first answer :

"There are 8 big fish for every 18 total fish."

Second answer :

"There are 4 big fish for every 9 total fish."

You're welcome, hope this works!
