Question

aflati nr care lipseste 285 :a=5
a:3=314
a:6=41 rest 2
852:a=7 rest 5
517:a=4 rest 1
a:4=142 rest 2

Answer 1

285 : a = 5
a = 285 : 5
a = 57

a : 3 = 314
a = 314 x 3
a = 942

a : 6 = 41 rest 2
a = 41 x 6 + 2
a = 248

852 : a = 7 rest 5
a = (852 - 5 ) :7 
a = 847  : 7
a = 121

517 : a = 4 rest 1
a = ( 517 - 1 ) : 4
a = 516 : 4
a = 129

a : 4 = 142 rest 2
a = 142 x 4 +2
a = 570
