Question

Fie proportia 3/4=6/8.Scrieti:
a)trei proportii derivate cu aceeasi termeni
b)patru proportii derivate cu termeni schimbati,utilizand numai adunarea si scaderea
c)patru proportii derivate cu termeni schimbati,folosind numai inmultirea si inpartirea​

Answer 1

a)3/6 = 4/8

8/6 = 4/3

4/3 = 8/6

b)3+4/4=6+8/8

=7/4=14/8

3/4+3=6/8+6

=3/7=6/14

3/4-3 = 6/8-6

=3/1 = 6/2

c)3×2/4 = 6×2/8

=6/4 = 12/8

3/4×2 = 6/8×2

=3/8=6/16

3/4=6÷2/8÷2

=3/4 = 3/4

3÷3/4 = 6÷3/8

= 1/4 = 2/8
