no.
The fraction will increase.
add half the denominator to the numerator
No because you have too multiply the numerator and denominator by the the same number to have an equivalent fraction.
To double a fraction double the numerator and keep the denominator unchanged.
To convert a mixed fraction to an improper fraction: Multiply the whole number by the denominator, and add the numerator. This will be the numerator of the result. Copy the denominator without changes to the denominator of the result.
By finding their lowest common denominator
multiply the denominator by the whole number then add the numerator and you have an improper fraction
Multiply the whole number by the denominator. Add the product to the numerator of the proper fraction. The sum is the numerator of the improper fraction. The denominator will stay the same.
Multiply the denominator by the whole number, then add the numerator by the answer you got from multiplying. Last, you slide the denominator over.
Because it tells you how much the fraction is out of.
Just simply add/subtract the numerators then copy the denominator.
To add a negative fraction to a mixed fraction, first convert the mixed fraction to an improper fraction. Then, find a common denominator for both fractions. Next, add the numerators and keep the common denominator. Finally, simplify the resulting fraction if needed. If the negative fraction has a smaller absolute value than the mixed fraction, you may need to borrow or regroup to ensure proper subtraction.
