-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.

To find the largest number that, when divided into both 63 and 75, leaves a remainder of three, you can use the concept of greatest common divisor (GCD) or greatest common factor (GCF). The GCD of 63 and 75 is the largest number that can evenly divide both numbers. To find it, you can use the Euclidean algorithm: Start with the two numbers: 63 and 75. Divide 75 by 63: 75 ÷ 63 = 1 with a remainder of 12. Now, replace the larger number (75) with the remainder (12) and keep the smaller number (63) as is: 63 and 12. Repeat the process: 63 ÷ 12 = 5 with a remainder of 3. Again, replace the larger number (63) with the remainder (3) and keep the smaller number (12) as is: 12 and 3. Repeat once more: 12 ÷ 3 = 4 with no remainder. Now that you have reached a point where the remainder is 0, the GCD is the last non-zero remainder, which is 3. So, the largest number that, when divided into both 63 and 75, leaves a remainder of three is 3.

Expressed as a mixed number in its simplest form, 63/5 is equal to 12 3/5 or twelve and three fifths.
5 and 1/4

63 x 12 = 756
The easiest way to tell if 63 ia a composite number is to determine if 3 will divide evenly into the digits when they are added together. 63 6 + 3 = 9. 9 is divisible by 3. 63 is a composite number. If you want to know what composite number will divide evenly into 63, you can list the factor pairs: 1 x 63 3 x 21 7 x 9 1, 3, and 7 are prime numbers. 9, 21, and 63 are the factors of 63 that are composite numbers.

3*N + 12 = 63 or 3*(N + 12) = 63 From the wording, the first is more likely but it gives rise to a fractional solution. If you are at a stage where you are learning to generate such equations, fractional answers are less likely.
