Jawaban:

Nomor 3

$tt = frac{1}{4} + frac{2}{5} times frac{3}{4} div ( frac{2}{5} - frac{2}{7} )$

$tt = frac{1}{4} + frac{6}{20} div ( frac{14}{35} - frac{10}{35} )$

$tt = frac{1}{4} + frac{3}{10} div frac{4}{35}$

$tt = frac{1}{4} + frac{3}{10} times frac{35}{4}$

$tt = frac{1}{4} + frac{105}{40}$

$tt = frac{2}{8} + frac{21}{8}$

$tt = frac{23}{8}$

$boxed{tiny tt = 2 frac{7}{8} }$

$tt = (1 frac{3}{4} - frac{4}{5} ) div frac{7}{8}$

$tt = ( frac{7}{4} - frac{4}{5} ) div frac{7}{8}$

$tt = ( frac{35}{20} - frac{16}{20} ) div frac{7}{8}$

$tt = frac{19}{20} div frac{7}{8}$

$tt = frac{19}{20} times frac{8}{7}$

$tt = frac{152}{140}$

$tt = frac{38}{35}$

$boxed{tiny tt = 1 frac{3}{35} }$
