Question

Va rog multttttttttttttttttt!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Punctul a

Answer 1

5/2 : 5/7 = 5/2 x 7/5 = 7/2
6/10 : 11/5 = 6/10 x 5/11 = 6/2 x 1/11 = 6/22 = 3/11
4/9 : 7/3 = 4/9 x 3/7 = 4/3 x 1/7 = 4/21
8/15 : 11/12 = 8/15 x 12/11 = 8/5 x 4/11 = 32/55
5/11 : 13/5 = 5/11 x 5/13 = 25/143

Answer 2

a) 5/2 : 5/7= 5/2 x 7/5= 7/2
b) 6/10 : 11/5 = 6/10 x 5/11 = simplific 5 si 10 prin 5 = 6/2 x 1/11= simplific prima fractie prin 2 = 3/1 x 1/11= 3/11
c) 4/9 : 7/3 = 4/9 x 3/7 = simplific 3 si 9 prin 3 = 4/3 x 1/7 = 4/21
d) 8/15 : 11/12 =8/15 x 12/11 = simplific 15 si 12 prin 3 = 8/5 x 4/11 = 32/55
e) 5/11 : 13/5 = 5/11 x 5/13 = 25/143
