Question

ex 2 dațim un exemplu doar atat

Answer 1

40÷3=13,3 ;/108÷8= 13,5

Answer 2

a)d = 15 x a + 13
a = 2
d = 30 + 13 = 43
43 : 15 = 2 rest 13

b) d = 20 x a + 13
a = 2
d = 40 + 13 = 53
53 : 20 = 2 rest 13

c) d = 40 x a + 13
a = 2
d = 40 x 2 + 13 = 93
93: 2 = 40 rest 13

d) d = 108 x a = 13
a = 2
d = 108 x 2 + 13 = 216 + 13 = 229
229 : 108 = 2 rest 13

e) d = 412 x a + 13
a = 2
d = 412 x 2 + 13 = 824 + 13 = 837
837 : 412 = 2 rest 13

f) d = 12300 x a + 13
a = 2
d = 24600 + 13 = 24613
24613 : 12300 = 2 rest 13
