Question

/- to kreska ulamkowa czy ktos pomorze mi to obliczyc 1/5+0,5= ,1/3-0,1= ,1cala i 1/3 x2= ,5całych i 10/11: 5 ,(1/2)do potegi 3=

Answer 1

1/5+0,5= 2/10 + 0,5 = 0,2 + 0,5 = 0,7

1/3-0,1= 1/3 - 1/10 = 10/30 - 3/30 = 7/30

1cala i 1/3 x2=  4/3 * 2/1 = 8/3 = 2 i 2/3

5całych i 10/11: 5 = 65/11 : 5/1 = 65/11 * 1/5 = 13/11 = 1 i 2/11

(1/2)do potegi 3= 1/2 * 1/2 * 1/2 = 1/8
