Question

suma tuturor numerelor care impartite la 7 dau catul 5 este egal cu:
va rog spunetimi cat face dau coroane !!!!​

Answer 1

a : 7 = 5 rest 0

a = 5 × 7 + 0

a = 35 + 0

a = 35

b : 7 = 5 rest 1

b = 5 × 7 + 1

b = 35 + 1

b = 36

c : 7 = 5 rest 2

c = 5 × 7 + 2

c = 35 + 2

c = 37

d : 7 = 5 rest 3

d = 5 × 7 + 3

d = 35 + 3

d = 38

e : 7 = 5 rest 4

e = 5 × 7 + 4

e = 35 + 4

e = 39

f : 7 = 5 rest 5

f = 5 × 7 + 5

f = 35 + 5

f = 40

g : 7 = 5 rest 6

g = 5 × 7 + 6

g = 35 + 6

g = 41

35 + 36 + 37 + 38 + 39 + 40 + 41 =

71 + 37 + 38 + 39 + 40 + 41 =

108 + 38 + 39 + 40 + 41 =

146 + 39 + 40 + 41 =

185 + 40 + 41 =

225 + 41 = 266 => suma numerelor
