3per4+1per3= 2per3+5per6= 1per4+3per8= 2per6+5per9=

3/4 + 1/3
= 6/12 + 5/12
= 11/12


2/3 + 5/6
= 4/6 + 5/6
= 9/6 = 3/2

1/4 + 3/8
=3/8 + 4/8
=7/8

2/6 + 5/9
= 11/54 + 30/54
=41/54


smg membantu/ maaf kl salah

[tex] \frac{2}{6} + \frac{5}{9} \\ = \frac{18 + 30}{54} \\ = \frac{48}{54} \div \frac{2}{2} \\ = \frac{24}{27} \div \frac{3}{3} \\ = \frac{8}{9} ..[/tex]
semoga membantu..
