Step-by-step explanation:
[tex]\dfrac{3}{7}=\dfrac{3}{7}\cdot\dfrac{2}{2}=\dfrac{6}{14}\\\\\dfrac{3}{7}=\dfrac{3}{7}\cdot\dfrac{3}{3}=\dfrac{9}{21}\\\\\dfrac{3}{7}=\dfrac{3}{7}\cdot\dfrac{4}{4}=\dfrac{12}{28}\\\\\dfrac{3}{7}=\dfrac{3}{7}\cdot\dfrac{5}{5}=\dfrac{15}{35}\\\vdots\\\\\dfrac{3}{7}=\dfrac{3}{7}\cdot\dfrac{10}{10}=\dfrac{30}{70}\\\vdots\\\\\dfrac{3}{7}=\dfrac{3}{7}\cdot\dfrac{100}{100}=\dfrac{700}{300}\\\vdots[/tex]
