How many quavers equal a semibreve tied to a crotchet tied to a quaver?

A semibreve equals 4 beats, a crotchet equals 1 beat, and a quaver equals half a beat. When you tie a semibreve to a crotchet and then to a quaver, you combine their durations: 4 beats (semibreve) + 1 beat (crotchet) + 0.5 beat (quaver) equals 5.5 beats total. Since each quaver is half a beat, 5.5 beats equals 11 quavers.
