There were 17 ducks on a pond. 7 flew away. What fraction of the ducks were left?

10/17

To find the fraction of ducks that were left, we need to subtract the number of ducks that flew away from the initial number of ducks, and then express it as a fraction.

Step 1: Start with the initial number of ducks,
Initial number of ducks = 17

Step 2: Subtract the number of ducks that flew away,
Number of ducks that flew away = 7
Ducks left = Initial number of ducks - Number of ducks that flew away
= 17 - 7
= 10

Step 3: Express the result as a fraction,
Fraction of ducks left = Ducks left / Initial number of ducks
= 10 / 17

So, the fraction of ducks that were left is 10/17.
