Given numbers: 2.5 and 2.5 repeating
1. Convert 2.5 to a fraction:
2.5 = 2 + \frac{5}{10} = 2 + 0.5 = 2.5
2. Convert 2.5 repeating to a fraction:
Let \(x = 2.5\overline{5}\)
Multiply both sides by 10:
10x = 25.5\overline{5}
Subtract the original \(x\) from this equation:
10x - x = 25.5\overline{5} - 2.5\overline{5}
9x = 23
Solve for \(x\):
x = \frac{23}{9}
2.5\overline{5} = \frac{23}{9}
3. Compare the numbers:
2.5 = 2.5
2.5\overline{5} > 2.5
Therefore,
2.5\overline{5}
