(4 7/9 - 1 1/2) - (15/16 - 1/24) = ?

4 7 / 9 = (4 × 9 + 7)/9 = 43/9

1 1/2 = (1 × 2 + 1)/2 = 3/2

(43/9 - 3/2) - (15/16 - 1/24) =

59/18 - 43/48 =

343/144

( 4intregi 7/9-1intreg1/2 )-(15/16-1/24)=

[(4×9+7)/9 -3/2]-(45/48-2/48)=

(43/9-3/2)-43/48=

(86/18-27/18)-43/48=

59/18-43/48=

472/144 - 129/144=343/144
