Jawaban:

 	t2 frac{1}{4}  + 4 frac{2}{3}  - 3 frac{1}{4}

 	t = (2 + 4 - 3) frac{(3 :  +  :8  :  -  : 3)}{12}

 	t = (6 - 3) frac{(11 :  -  : 3)}{12}

 	t = 3 frac{8}{12}

 	t = 3 frac{2}{3}

..

 	t2 frac{4}{7}  	imes 3 frac{1}{9}  div  frac{4}{5}

 	t =  frac{18}{7}  	imes  frac{28}{9}  	imes  frac{5}{4}

 	t = 10
