Image to Crop Evaluate 4.57

Evaluate the repeated piece

The repeated piece 57 has a length of 2
Therefore, we setup two equations.
Equation 1: x = 4.57
Equation 2: 100x = 102 100x 4.57
100x = 100 x 4.57
100x = 457
Therefore, we have 100x - x = 457 - 4.57
99x = 457

Divide each side by 99


x  =  457
  99

457/99
