Question

10 transformari : finite si infinite periodice simple . Urgent ! Dau coronitaaaa Va rog .

Answer 1

1) 2,3 = 23/10
2) - 1,92 = - 192 / 100 = - 96 / 50 = - 48/25
3) 0, 157 = 157 / 1000
4) 0,6 = 6/10 = 3/5
5) 0,23 = 23 /100
6) 12,37 = 1237/100
7) 0,(3) = 3/ 9 = 1 /3
8)  1,(3) = 1 intreg 3/9 = 1 intreg 1/3 = ( 1·3 + 1) /3 = 4/3
9) 23,( 5) = 23 intregi 5/9 = ( 23·9 + 5) / 9 = 212/9
10) 61,23(5) = 61 intregi ( 235 - 23) /900 = 61 intregi 212/900 = ( 61·900 + 212) / 900 = 55112/900
