Quick questions on Rhythm, metre and time signatures explained: O-Level Music

A time signature has two numbers. The lower number names the beat unit (4 means the beat is a crotchet, 8 means the beat is a quaver). The upper number says how many of those units make a bar. So $\frac{3}{4}$ means three crotchet beats per bar, and $\frac{2}{2}$ means two minim beats per bar.

Beaming joins quavers and shorter notes with a thick horizontal beam to show the beat groupings clearly. Notes are beamed in beat-sized groups so the eye sees where each beat starts, which is why $\frac{6}{8}$ is beamed in two groups of three rather than three groups of two.

State what each number in a time signature tells you, using $\frac{3}{4}$ as your example. [2 marks]
