1 and 3 can go into 12 and 63.
75
-12 + 75 = 63 So if minus 12 is increased by 75 the new number is 63 If the question was 75 percent, the number would be 36.
Nine will go into 63 seven times.
12 with 3 remaining 63 - 3 = 60 = 5 x 12
Seven goes into both 63 and 77
3 = 63/21 = 150/50
It is 1
63 - 3 = 60 = 5 x 12 12 times with 3 remaining
There are an infinite number of them. The smallest one is 63, and the rest are all the multiples of 63.
The number 63 can be evenly divided by 1, 3, 7, 9, 21, and 63.
