tolong bantu aku ngerjain ini ya kk
Bagian pertama
[tex]\large \boxed{\begin{aligned}\sf \frac{2}{5} + \frac{1}{5} &=\sf ... \\ \sf \frac{2}{5} + \frac{1}{5} &=\sf \frac{2 + 1}{5} \\ \sf &= \sf \frac{ 3}{5} \end{aligned}}[/tex]
Jadi, [tex] \begin{aligned} \sf \frac{2}{5} + \frac{1}{5} \end{aligned} = \begin{aligned}\bf{ \red{\frac{3}{5} }} \end{aligned}[/tex]

Bagian kedua
[tex]\large \boxed{\begin{aligned}\sf \frac{4}{9} + \frac{3}{9} + \frac{1}{9} &=...\sf \\ \sf\frac{4}{9} + \frac{3}{9} + \frac{1}{9} &=\sf \frac{4 + 3 + 1}{9} \\ \sf &= \sf \frac{8}{9}\end{aligned}}[/tex]
Jadi, [tex] \begin{aligned} \sf\frac{4}{9} + \frac{3}{9} + \frac{1}{9} = \bf \red{ \frac{8}{9} }\end{aligned}[/tex]
