Juan y david beban leche. (beber) the verb is conjugated correctly. the verb is not conjugated correctly.

The web is indeed conjugated incorrectly.

The correct way of saying it would be:

Juan y David beben leche.

The mistake was that before it was beban with an A instead of an E

Since the original word is beber you know that you will be using E since it ends in the -er form.

Hope this helps! :3
