1. Add 4.36 and 4.54 together:
4.36 + 4.54 = 8.90
2. Divide the sum by 2 to find the average:
8.90 / 2 = 4.45
Therefore, 4.45 is the number that lies exactly in the middle of 4.36 and 4.54. This is because it is the average of the two given numbers, making it equidistant from both 4.36 and 4.54 on the number line.
