$7 frac{3}{4} - 2 frac{1}4 - 2 frac{1}{3} = ...$

$= frac{4 times 7 + 3}{4} - frac{4 times 2 + 1}{4} - frac{3 times 2 + 1}{3}$

$= frac{28 + 3}{4} - frac{8 + 1}{4} - frac{6 + 1}{3}$

$= frac{31}{4} - frac{9}{4} - frac{7}{3}$

$= frac{22}{4} - frac{7}{3}$

$= frac{(22 times 3) - (7 times 4)}{4 times 3}$

$= frac{66 - 28}{12}$

$= frac{ 38}{12} to{ sf{sederhanakan}}$

$= boxed{ bold{3 frac{1}{6}}}$

$7 frac{3}{4} - 2 frac{1}{4} - 2 frac{1}{3} = frac{31}{4} - frac{9}{4} - frac{7}{3} = frac{93 - 27 - 28}{12} = frac{38}{12} = 3 frac{2}{12} = 3 frac{1}{6}$

Maaf kalau salah ✌
