See explanation.

This question can be done by unitary method for better understanding.

Since there are 3 beats in 1 movement in first measure.

Therefore there are 1 beat in #1/3# measures.

Therefore there are #x# beats in #x/3# measures.

Similarly there are #b# beats in #b/4# measures.

As per questions, 'at least' is used so total no of counted measures, #x/3 + b/4# , could be equal or more than 446.

So #x/3 + b/4 >= 446#
