Question

înlocuieste literele cu numere naturale astfel inca n/9 +3/9=1; a/7+5/7<8/7; b/7+5^7 <_9/7

Answer 1

n/9 + 3/9 = 1
(n + 3)/9 = 1
n + 3 = 9
n = 6

a/7 + 5/7 < 8/7
(a + 5) < 8
a < 3
a ∈ {0, 1, 2}

b/7 + 5/7 < -9/7
b + 5 < -9
b < - 14 nu poate fi numar natural...

Answer 2

6/9+3/9=9/9=1
2/7+5/7<8/7 si 1/7+5/7<8/7 a=1si2
nu inteleg pe al 3-lea
