Va rog dau coroana ​

Answer 1

a. 8/21 x 8x4+3/4=8/21 x 35/4=
8 cu 4 se simplifica si avem 2/3 x 5=10/3

b.6x3+2/3 x 9/16=20/3 x 9/16=simplificam 3 cu noua si 20 cu 16 si da 5 x 3/4=15/4

c.9/4 x 20/27=5/3

d.7/25 x 25/6= simplificam 25 cu 25
7 x 1/6=7/6

e.16/7 x 21/32=3/2

F.16/27 x 45/8= 2/3 x 5=10/3
