Question

VA ROG MULT SCRIETI 1 SI 2 TOT CE STITI DAU 20 de puncte

Answer 1

Răspuns:

1. a) 17/4= 4,25    le imparti

7/8= 0,875

99/25= 3,96

...

2.

25,75=  $\frac{2575}{100} = \frac{103}{4}$ (2575 si 100 se simplifica prin 25

2,575= $\frac{2575}{1000} = \frac{103}{40}$   (2575 si 1000 se simplifica prin 25

0,2575= $\frac{2575}{10000} = \frac{103}{400}$ (2575 si 10000 se simplifica prin 25

257,5= $\frac{2575}{10} = \frac{515}{2}$   (2575 si 10  se simplifica prin 5)

0,3= 3/10

0,30= 30/100=3/10

3,84= $\frac{384}{100} =\frac{96}{25}$   ( 384 si 100 se simplifica prin 4)

0, 001= $\frac{1}{1000}$

0,0002= $\frac{2}{10000} = \frac{1}{5000}$
