VA ROG FRUMOS SA MA AJUTATI URGENT!

Answer 1

6⁽²/14 = 21⁽³/48

3/7 = 7/16

3*16 = 7*7

48 = 49 (f)

2/10 = 6/31

1/5 = 6/31

30 = 31 (f)

4/5 = 2/25

100 = 10 (f)

1.2/1.4 = 3/1.5 (f)

a 2a fractie este supraunitara

0.08/1.2 = 1/1.5

1.2 = 0.12 (f)

4.5/18 = 7/28

126 = 126 (a)

7/9 = 2.8/3.5

24.5 = 25.2 (f)

0.8/1.2 = 1.5/2.25

1.8 = 1.8 (a)

1.(3)/1.1(6) = 1.4/1.24

12/9*90/105 = 14/10*100/124

4/3*7/6 = 7/5*25/31

14/9 = 35/31

434 = 315 (f)
