Answer 1

0,25+0,3=0,85
1/3-0,1=1/3 - 1/10 = 10/30 -3/30 = 7/30
1/2+0,308=0,5+0,308 = 0,808
2,71-2/5=2,71-0,4 = 2,31
1/4*0,4=0,25*0,4 = 0,1
1 i 3/4:0,1=1,75:0,1 = 17,5
0,6:3/4=0,6:0,75 = 0,8
2/5+0,77=0,4+0,77 = 1,17
1,75-5/6=1 i 3/4 - 5/6 = 1 i 9/12 - 10/12 = 11/12
2/15*0,75=2/15*3/4 = 6/60 = 1/10
3 i 3/4:0,05 = 3,75:0,05 = 75
2 i 1/4*2/3 = 9/4*2/3 = 18/12 = 1 i 1/2
5/6+1 i 2/3=5/6+ 1 i 4/6 = 1 i 9/6 = 2 i 1/2
1-1/2*1/3=1 - 1/6 = 5/6
3 i 2/7+6=9 i 2/7
2 i 4/5:7/2=14/5*2/7 = 28/35 = 4/5
1 i 9/10+1/5=1,9+0,2 = 2,1
1 i 1/5 *1/3=6/5*1/3 = 6/15 = 2/5
3 i 1/2*2/3 :7=7/2*2/3*1/7 = 14/42 = 1/3
1 i 1/5+3/10=1,2+0,3 = 1,5
5-2/3*1/2=5 - 1/3 = 4 i 2/3
1 i 5/12:1/2=17/12*2 = 34/12 = 2 i 10/12 = 2 i 5/6
5 i 1/8- 3 i 1/2=5 i 1/8 - 3 i 4/8 = 1 i 3/8


kilku przykładów nie zrobiłam, bo chyba coś napisałaś nie tak
ale jak poprawisz to dodam odpowiedzi:)
