Odpowiedź:
0,2 + 3/4 = 0,2 + 0,75 = 0,95
1/3 - 0,2 = 1/3 - 2/10 = 10/30 - 6/30 = 4/30 = 2/15
1/2 + 0,328 = 0,5 + 0,328 = 0,828
2/7 * 0,3 = 2/7 * 3/10 = 6/70 = 3/35
1 i 3/4 : 0,1 = 7/4 : 1/10 = 7/4 * 10/1 = 35/2 = 17 i 1/2
0,6 : 3/4 = 6/10 : 3/4 = 6/10 * 4/3 = 4/5
b)1/3-0,2=1/3-2/10=10/30-6/30=4/30=2/15
c) 1/2+0,328=0,5+0,328=0,828
d)2/7•0,3=2/7•3/10=6/70=3/35
e)1 i 3/4:0,1=7/4:1/10=7/4•10/1=35/2=17 i 1/2
f) 0,6:3/4=6/10:3/4=6/10•4/3=4/5
