Alenkinab [10]

Answer:

\boxed{3.1 \, \%}

Step-by-step explanation:

The formula for calculating percentage is

\text{Percentage} = \dfrac{\text{Part}}{\text{Whole}} \times 100 \, \%

The "part" is the electricity payment.

The "whole" is Ramon's earnings.

\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}
