Answer 1

a) 30/12 =5/2

b) 28/42=14/21=2/3

c) 32/40=4/5

d) 45/27=15/9=5/3

e)36/48=18/24=3/4

f)48/54=24/27=8/9

Answer 2

Răspuns:

a)$\frac{30}{12} =$ ( simplificam cu 6 )

$\frac{5}{2}$ = 2,5

b) $\frac{28}{42} =$ (simplificam cu 14 )

$\frac{2}{3}$ = 0,(6)

c) $\frac{32}{40}=$ ( simplificam cu 8 )

$\frac{4}{5}$ = 0,8

d) $\frac{45}{27} =$ (simplificam cu 9 )

$\frac{5}{3}$ = 1,(6)

e) $\frac{36}{48} =$ ( simplificam cu 12 )

$\frac{3}{4}$ = 0,75

f) $\frac{48}{54} =$ ( simplificam cu 6 )

$\frac{8}{9}$ = 0,(8)
