[3 1/4 + 2/3 : 5/6] tolong do bantu ya

[3 1/4 + 2/3 : 5/6]
= [(3×4)+1]/4 + 2/3 : 5/6
= 13/4 + 2/3 : 5/6
= 13/4 + 2/3 × 6/5
= 13/4 + 4/5
= 65+16 /20
= 81/20

Penyelesaian :

$= (3 frac{1}{4} + frac{2}{3} div frac{5}{6} ) \ \ = frac{13}{4} + frac{2}{3} div frac{5}{6} \ \ = frac{13}{4} + frac{2}{3} times frac{6}{5} \ \ = frac{13}{4} + 2 times frac{2}{5} \ \ = frac{13}{4} + frac{4}{5} \ \ = frac{81}{20}$
