If there are 10 fewer frogs than snakes in the forest, and you know there are 7 frogs, you can determine the number of snakes using this information.
Let's use "S" to represent the number of snakes and "F" to represent the number of frogs. According to the information provided:
F = S - 10
You know that there are 7 frogs, so you can substitute F with 7 in the equation:
7 = S - 10
Now, solve for S (the number of snakes):
S = 7 + 10
S = 17
So, there are 17 snakes in the forest.
