Oblicz:
a)5 5/9 : (5 5/6-10)=
b)4 4/9+(-5/6)=
(to 5/9 itp. to jest jakby co ulamek ;) )
5⁵/₉;(5⅚-10)=⁵⁰/₉:(-4⅙)=⁵⁰/₉×(-⁶/₂₅)=-⁴/₃=-1⅓
4⁴/₉+(-⅚)=4⁴/₉-⅚=4⁸/₁₈-¹⁵/₁₈=3²⁶/₁₈-¹⁵/₁₈=3¹¹/₁₈
a)5 5/9 : (5 5/6-10)= 50/9 : (-4 1/6) = 50/9 : (-25/6) = 50/9 * (-6/25) = - 4/3 = - 1 1/3
b)4 4/9+(-5/6)= 40/9 - 5/6 = 80/18 - 15/18 = 65/18 = 3 11/18
