Question

Va rog ajutați-ma la exercițiul 6.M-am blocat

Answer 1

1 --- 3

2 --- 4

3 --- 5

5 --- 6

7 --- 7

6 --- 8

4 --- 9

2 --- 10

Trebuie sa aflam cati elevi sunt

1+2+3+5+7+6+4+2=30

p% * 30 = 6 ( 6 reprezinta nr elevilor care au luat nota 8 )

p/100 * 30 = 6

30p/100 = 6

3p/10= 6

3p = 60

p = 20 %
