I think you mean 'Why do frogs lay egg?' If so, they lay egg because they are amphibians. And all amphibians lay eggs. Frogs lay their eggs in clusters. Toads lay eggs in a line.
Frogs lay eggs that hatch into tadpoles. Tadpoles grow up and become frogs.
Frog eggs. Frogs lay eggs, and the eggs hatch into tadpoles. Then the tadpoles turn into frogs.
Frogs lay eggs rather than giving birth to live young. They lay sometimes hundreds of them and some eventually hatch into tadpoles and become frogs themselves.

Frogs hatched from eggs. Eggs hatch into fishlike young called tadpoles which grow and eventually undergo metamorphosis, a change in body form, to become adults. But some frogs do not have a tadpole stage, instead, tiny froglets hatch directly from the eggs.
Yes a Frog will lay hundreds of eggs, know as Frog spawn, from each egg a tadpole (baby frog) should hatch.

Tadpoles do not lay eggs at all. Tadpoles are the young frogs or toads that hatch from eggs.
only a few hundred will survive after they hatch others will die before they hatch
There are several hundred frogs that do not require water to lay their eggs. They use direct development to reproduce so the young hatch as fully formed frogs instead of tadpoles.
Frogs are sexual. They reproduce sexually, and all hatch from eggs. Frogs lay eggs in water, and the eggs hatch into tadpoles that grow into frogs.
They don't. They lay eggs that hatch into tadpoles that develop into frogs. They are not cared for, it is every tadpole for himself.
