2 4 5


b)1_ d)-10 f)50
9 5 44

determine a fraçao

a)0,6666... c)1,555... e)1,1666...

b)o,7777... d)2,444... f)3,030303...

Answer 1

-1,28 = -128/100
4,458 = 4458/1000
56,6789 = 566789/1000
a)0,6666... = 6/9  
b)0,7777... = 7/9
c)1,555... = 9/9 + 5/9 = 14/9
d)2,444... = 18/9 + 4/9 = 22/9
e)1,1666... = 15/90 + 90/90 = 105/90
f)3,030303... = 1/33 + 99/33 = 100/33
