In January, there are 5 Mondays and 4 Fridays. The children read $\frac{3}{4}$ hour on each Monday and $\frac{1}{8}$ hour on each Friday. Total reading time is $5 \times \frac{3}{4} + 4 \times \frac{1}{8} = \frac{15}{4} + \frac{4}{8} = \frac{15}{4} + \frac{1}{2} = \frac{15}{4} + \frac{2}{4} = \frac{17}{4} = 4 \frac{1}{4}$ hours.
