d)180/90
e)12/30
f)56/700
g)375/1250

Va rog urgent,trebuie să fac tema acum!!!

Answer 1

$a) \frac{128}{200} = \frac{128 : 8}{200 : 8} = \frac{16}{25} = 0,64$

$b) \frac{150}{60} = \frac{150 : 30}{60 : 30} = \frac{5}{2} = 2,5$

$c) \frac{36}{400} = \frac{36 : 4}{400 : 4} = \frac{9}{100} = 0,09$

$d) \frac{180}{90} = \frac{180 : 90}{90 : 90} = \frac{2}{1} = 2$

$e) \frac{12}{30} = \frac{12 : 6}{30 : 6} = \frac{2}{5} = 0,4$

$f) \frac{56}{700} = \frac{56 : 28}{700 : 28} = \frac{2}{25} = 0,08$

$g) \frac{375}{1250} = \frac{375 : 125}{1250 : 125} = \frac{3}{10} = 0,3$

Answer 2

a) simplificam fractia cu 8 => 16/25 = 0,64

b) simplificam 0 cu 0 => 15/6 => simplificam cu 3 => 5/2 = 2,5

c) simplificam cu 4 => 9/100 = 0,09

d) simplificam 0 cu 0 => 18/9 = 2

e) simplificam cu 6 => 2/5 = 0,4

f) simplificam cu 28 => 2/25 = 0,08

g) simplificam cu 125 => 3/10 = 0,3
