[tex]1.) \: \frac{4}{9} + \frac{8}{7} = ...[/tex]
Penyelesaian :
[tex]\frac{4}{9} + \frac{8}{7} [/tex]
[tex] = \frac{4 \times 7}{9 \times 7} + \frac{8 \times 9}{7 \times 9} [/tex]
[tex] = \frac{28}{63} + \frac{72}{63} [/tex]
[tex] = \frac{28 + 72}{63} [/tex]
[tex] = \frac{100}{63} [/tex]
[tex] = 1 \frac{37}{63} [/tex]
