From the pie chart, find the percentage of children with temperature > 37.5°C.

This percentage corresponds to 27 children (given).

Find the percentage for temperature < 37.0°C from the chart, then use proportion:
\(\frac{\text{percentage for } < 37.0^\circ\text{C}}{\text{percentage for } > 37.5^\circ\text{C}} \times 27\).

From the chart, the proportion gives 102 children.

Final Answer: 102
