Math pecahan~

$1 frac{4}{7} + frac{1}{2} - frac{5}{8} =$

$frac{11}{7} + frac{1}{2} - frac{5}{8}$

$frac{11}{7} times frac{8}{8} + frac{1}{2} times frac{28}{28} - frac{5}{8} times frac{7}{7}$

$frac{88}{56} + frac{28}{56} - frac{35}{56}$

$frac{116}{56} - frac{35}{56}$

$frac{81}{56}$

$1 frac{25}{56}$

———–

$frac{12}{3} times frac{14}{10}$

$frac{168}{30}$

$frac{84}{15}$

$5 frac{9}{15}$

$5 frac{3}{5}$

= 1 4/7 + 1/2 – 5/8

= 88/56 + 28/56 – 5/8

= 116/56 – 35/56

= (116 – 35)/56

= 81/56

= 1 25/56

= 12/3 × 14/10

= 168/30

= 84/15

= 5 3/5
