Przedstaw liczbę w postaci ułamka zwykłego
f)41,7(9)
g)0,(369)
h)2,1(52)
f)41,7(9)=41,7 + 0,0(9)=41,7+ 0,1 * 0,(9)=41 7/10 + 1/10 * 9/9=
=41 7/10 +1/10=41 8/10=41 4/5
======================
g)0,(369)=369/999=41/111
h)2,1(52)=2,1 + 0,0(52)=2,1 + 0,10 * 0,(52)=2 1/10 + 1/10 * 52/99=
=2 99/990 + 52/990= 2 151/990
