(1 1/2+2 2/3) :5/6- (3 1/3- 1 1/4) : 2 1/12 polecenie to obliczyć :D

Answer 1

(3/2+8/3):5/6-(10/3-5/4):25/12=

=(9/6+16/6):5/6-(40/12-15/12):25/12=

=25/6:5/6-25/12:25/12=

=25/6*6/5-25/12*12/25= (tu się ładnie poskraca)

=5-1=4

Answer 2

(1 1/2+2 2/3) :5/6- (3 1/3- 1 1/4) : 2 1/12 =

(1 3/6 + 2 4/6) * 6/5 - (3 4/12 - 1 3/12) : 25/12 =

3 7/6 * 6/5 - 2 1/12 * 12/25 =

25/6 * 6/5 - 25/12 * 12/25 = 5 - 1= 4
