Answer:
Step-by-step explanation:
To see if this is a true statement, we need to get both fractions with the same denominator.
[tex]\frac{2}{7} = \frac{4}{14}[/tex]
Multiply both sides by 2
[tex]\frac{1}{2} = \frac{7}{14}[/tex]
Multiply both sides by 7
[tex]\frac{4}{14} + \frac{7}{14} = \frac{11}{14}\\\frac{11}{14} \neq \frac{3}{9}[/tex]
[tex]\frac{11}{14} = 0.7857... \\\frac{3}{9} = \frac{1}{3} = 0.333...[/tex]
0.333... ≠ 0.7857...
