jak coś to np.: 2/3 to jest ułamek

Answer 1

1.2,7-3 1/3-1,3-2/3-5,7+9,3= 2 21/30-3 10/30-1 9/30-20/30-5 21/30+9 9/30=

2 1/30- 2 1/30-15=-15

2.-10 3/4-3,4+1/7-0,25+3 2/3=-10 30/40-3 16/40+3/21-10/40+3 14/21=

-14 16/40+3 17/21=-14 84/210+3 170/210=-14 42/105+3 85/105=-11 62/105

3.-6  1/8-0,25+6,125-4 1/4=12 1/4- 4 2/4=7 3/4

4.-1,125+2,68+0,125+10,25+1,32-11=-1 1/8+2 68/100+1/8+10 1/4+1 32/100-11=-1+14 1/4-11=-12+14 1/2=2 1/2
