Stronger Acid 6C.21

How do you know that formic acid is stronger than acetic acid? What would be the reasoning?

acetic acid has a less stable conjugate base so it is a weaker acid.

Out of acetic acid and formic acid, formic acid is considered stronger because the CH3 in acetic acid is electron donating. The CH3 actually contributes electron density towards the O-H bond, making it harder to remove the H, and making acetic acid a weaker acid than formic acid

how does the Ch3 contribute electron density towards the O-H bond?
