To ensure that it has a few adult offspring. Mortality is very high for tadpoles, so the more of them the better.
If juvenile mortality is low, then an organism would be better off making a few large eggs so that the juveniles get to adulthood faster, decreasing the generation time.

Frogs produce huge amounts of eggs to ensure the continuation of their species as only one of five eggs will mature into a frog and return to breed. Frogs have many predators. Newts, fishes, snakes, aquatic insects like dragonfly nymphs, and aquatic birds enjoy eating frog embryos and tadpoles. Once frogs mature, they have more predators on land, such as snakes, bullfrogs, birds, fishes, turtles, crocodiles, and small mammals.

I guess it's because the eggs and the tadpoles are prey to a lot of animals. laying more eggs ensures that at least some survive to continue the species.

to ensure that a healthy population reaches adulthood so that they ensure continuity of the species.
the frogs are at a lower level in the foodchain. so they have many predators. if enough eggs arent layed sufficient numbers may not survive.

because most of the eggs get eaten by toads other frogs and fish

To guarantee survival. Most of the eggs, (in the wild), get eaten by scavengers!

To add this on; this is called R-selection.
