How many ODU1s are in an ODU2?

Working

ODU2 → 4 × ODU1

1. 4 × ODU1 in each ODU2 ITU-T G.709Four ODU1s. Each ODU1 takes two of the eight 1.25 Gbit/s tributary slots.

• 4 ODU1s

Leftover capacity

42.17342 Mbit/s of each ODU2 line rate (10.037273924 Gbit/s) sits outside 4 × 2.498775126 Gbit/s of ODU1 line rate (9.995100504 Gbit/s). That remainder is overhead, fixed stuff or justification. It is not another whole tributary.
