b) 4/3=20/?=?/6
c) 1/2=3/?=?/10
Am nevoie de ajutorul vostru!

Answer 1

a)
5/2=10/4=20/8
b)
4/3=20/15=8/6
c)
1/2=3/6=5/10

Answer 2

a) 5/2=?/4=20  amplificam prima data cu 2....apoi cu 4
$\frac{5}{2} = \frac{10}{4}=\frac{20}{8}$
b) 4/3=20/?=?/6  amplificam prima data cu 5....apoi cu 2
$\frac{4}{3} = \frac{20}{15}=\frac{8}{6}$
c)  1/2=3/?=?/10    amplificam prima data cu 3....apoi cu 5
$\frac{1}{2} = \frac{3}{6}=\frac{5}{10}$
