8/13-2/4=?4/9-2/8=? dan caranya

Jawaban:

1. $frac{3}{26}$

2. $frac{7}{36}$

1. $: frac{8}{13} - frac{2}{4} = frac{8}{13} - frac{2 div 2}{4 div 2} = frac{8}{13} - frac{1}{2} = frac{2 times 8 - 13 times 1}{26} = frac{3}{26}$

2. $frac{4}{9} - frac{2}{8} = frac{4}{9} - frac{2 div 2}{8 div 2} = frac{4}{9} - frac{1}{4} = frac{4 times 4 - 9 times 1}{36} = frac{7}{36}$
