We are asked to express the decimals in rational form

Let us first understand what is rational form

Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions.

An integer can be written as a fraction simply by giving it a denominator of one, so any integer is a rational number.

0.54 can be expressed in rational form by multiplying and dividing by 100 (here we used 100 since 0.54 has two digits after decimal point )

$0.54 = \frac{0.54 \times 100}{100} = \frac{54}{100}$

Similarly,

$4.23 = \frac{4.23 \times 100}{100} = \frac{423}{100}$
