NOMOR 1

$frac{4}{16} + frac{7}{8} - frac{15}{4}$

$= frac{4}{16} + frac{7 times 2}{8 times 2} - frac{15 times 4}{4 times 4}$

$= frac{4}{16} + frac{14}{16} - frac{60}{16}$

$= - frac{42 div 2}{16 div 2}$

$= - frac{21}{8}$

$= - 2 frac{5}{8}$

$:$

NOMOR 2

$frac{2}{6} + frac{5}{9} div frac{7}{3}$

$= frac{2 div 2}{6 div 2} + frac{5}{9} times frac{3}{7}$

$= frac{1}{3} + frac{15 div 3}{63 div 3}$

$= frac{1 times 7}{3 times 7} + frac{5}{21}$

$= frac{7}{21} + frac{5}{21}$

$= frac{12 div 3}{21 div 3}$

$= frac{4}{7}$

$:$

NOMOR 3

$frac{8}{5} div frac{1}{6} times frac{9}{5}$

$= frac{8}{5} times frac{6}{1} times frac{9}{5}$

$= frac{48}{5} times frac{9}{5}$

$= frac{432}{25}$

$= 17frac{7}{25}$
