Soal susah ka tolong ya (4 1/4 + 2 1/2 x 4 2/3 =

Jawab:

$= 4frac{1}{4} + 2frac{1}{2} times 4frac{2}{3}$

$= frac{17}{4} + frac{5}{2} times frac{14}{3}$

$= frac{17}{4} + frac{70}{6}$

$= frac{17 times 3}{4 times 3} + frac{70 times 2}{6 times 2}$

$= frac{51}{12} + frac{140}{12}$

$= frac{191}{12} = 15frac{11}{12}$
