Answer:
[tex]\boxed{3.1 \, \%}[/tex]
Step-by-step explanation:
The formula for calculating percentage is
[tex]\text{Percentage} = \dfrac{\text{Part}}{\text{Whole}} \times 100 \, \%[/tex]
The "part" is the electricity payment.
The "whole" is Ramon's earnings.
[tex]\begin{array}{rcl}\text{\% of earnings} & = & \dfrac{53.10}{1735} \times 100 \, \% \\\\& = & \mathbf{3.1 \, \%}\\\end{array}\\\boxed{\mathbf{3.1 \, \%}} \text{ of Ramon's earnings are on electricity}[/tex]
