operasi penjumlahan pecahan tolong di jawab

3. 4/6 + 3/5=20/30 + 18/30=38/30=3 8/30 =3 4/15

1.
[tex] \frac{2}{5} + \frac{1}{4} = \frac{8}{20} + \frac{5}{20} = \frac{13}{20} [/tex]
2.
[tex] \frac{3}{7} + \frac{2}{3} = \frac{9}{21} + \frac{14}{21} = \frac{23}{21} [/tex]
3.
[tex] \frac{4}{6} + \frac{3}{5} = \frac{20}{30} + \frac{18}{30} = \frac{38}{30} [/tex]
4.
[tex] \frac{2}{9} + \frac{1}{2} = \frac{4}{18} + \frac{9}{18} = \frac{13}{18} [/tex]

5.
[tex] \frac{3}{4} + \frac{1}{7} = \frac{21}{28} + \frac{4}{28} = \frac{25}{28} [/tex]
Semoga membantu belajarnya!! Jangan lupa jadikan terbaik yah!!
