The improper fraction is a fraction when the numerator is greater than or equal to the denominator
Given the number 4.2
It can be written as a mixed fraction as:
[tex]4.2=4+0.2=4+\frac{2}{10}=4\frac{2}{10}[/tex]And when converted to an improper fraction will become:
[tex]4\frac{2}{10}=\frac{10\times4+2}{10}=\frac{42}{10}[/tex]So, the numerator will be equal to 42
