Answer 1

Sa incerci sa le rezolvi si singur, fara sa te uiti pe foi.

Answer 2

4.c

5/1000=0,005

35/1000=0,035

235/1000=0,235

2016/10^3=2016/1000=2,016

143/10^4=143/10000=0,0143

2574/10^4=2574/10000=0,2574

18/10000=0,0018

5.a

$2 \frac{11}{10} = 2 \times 10 + 11 = \frac{31}{10} = 3.1$

$7 \frac{1}{10^{3} } = \frac{7 \times 1000 + 1}{1000} = \frac{7001}{1000} = 7.001$

$5 \frac{214}{10 ^{4} } = \frac{5 \times 10000 + 214}{10000} = \frac{50214}{10000} = 5.0214$

$12 \frac{3}{10^{5} } = \frac{12 \times 100000 + 3}{100000} = \frac{1200003}{100000} = 12.00003$

$1 \frac{435}{100} = \frac{1 \times 100 + 435}{100} = \frac{535}{100} = 5.35$

b. 4/5=0,8

83/2=41,5

53/4=13,25

17/25=0,68

7/20=0,35

$3 \frac{5}{8} = \frac{29}{8} = 3.625$

19/40=0,475

274/200=1,37
