Question

?÷4=5(ост.3), ?÷7=5(ост.4), ?÷3=8(ост.1), 37÷?=6(ост.1), 47÷?=4(ост.7), 28÷?=4(ост.4).....

Answer 1

х : 4 = 5 (ост.3)
х = 5 * 4 + 3
х = 23

 
х : 7 = 5 (ост.4)
х = 5 * 7 + 4
х = 39
 
 
х : 3 = 8 (ост.1)
х = 8 * 3 + 1
х = 25
 
 
37 : х = 6 (ост.1)
х = (37 - 1) : 6
х = 6
 
 
47 : х = 4 (ост.7)
х = (47 - 7) : 4
х = 10
 
 28 : х = 4 (ост.4)
х = (28 - 4) : 4
х = 6

Answer 2

5*4+3 = 23
5*7+4 = 39
8*3+1 = 25
(37-1):6 = 6
(47-7):4 = 10
(28-4):4 = 6
