The least common denominator for these two rational expression is

=7[tex]a^{2}[/tex]

Step-by-step explanation:

  • The two rational expressions are
  • [tex]\frac{4}{a^2}[/tex] [tex]\frac{3}{7a}[/tex]
  • finding the least common denominator, we take L.C.M

  •      [tex]\frac{4}{a^2}[/tex] [tex]\frac{3}{7a}[/tex]

The L.C.M is 7

Therefore, the largest number is [tex]a^{2}[/tex]

The least common denominator for these two rational expression is

=7[tex]a^{2}[/tex]
