The second.
Because the decimal system is based on 10 ("decem" = 10 )
Multiply the numerator and the denominator by the same number.
it is the Same Number Just 2,3,4.... Times As Much
a signed number is one that can be negative (have a sign) whereas an unsigned number will only be positive. due to less information, you can double the largest number storable in a signed integer to get the data available in an unsigned integer. However, PHP doesn't have unsigned integers, they're all signed.
To get an equivalent fraction, multiply both numbers by the same number. For example, multiplying by 2, you get 6/16.
The number is divided by 4.

It is equivalent to multiplying by the cube of that number.
Multiply the numerator and the denominator by the same number.
Because if you are multiplying a number, x, three times it is the formula of multiplying a cube!

If you assign -1 to a unsigned variable it will contain the biggest number its able to hold. For example if you assign -1 to a unsigned int it will be 4294967295 as its the biggest number a unsigned int can hold.
6/18 and 9/27......you can find out equivalent fractions by multiplying the numerator (top number) by the same number as the denominator (bottom number)
Doubling a number means multiplying it by 2. This is equivalent to adding the number to itself. Halving means dividing by 2. This is equivalent to multiplying by 1/2 (or by 0.5); since this is not an integer, it can't be reduced to addition.
#include<iostream> unsigned sum_of_digits(unsigned num) { unsigned sum = 0; do { sum += num%10; } while (num/=10); return sum; } int main() { unsigned number = 12345; unsigned sum = sum_of_digits (number); std::cout << "Sum of digits in " << number << " is " << sum << std::endl; }
Doubling a number is equivalent to multiplying by 2. Doubling twice (doubling, and then doubling the result again) is equivalent to multiplying by 4. (Also, doubling three times is the same as multiplying by 8, doubling 4 times is the same as multiplying by 16, etc.)
