multiply the denominator by the whole number then add the numerator and you have an improper fraction
you have to multiply the top and bottom number by the same number
To convert a mixed number to an improper fraction, multiply whole number part by the denominator of the fraction part, then add the numerator to the product. The result is the numerator of the improper fraction. The denominator remains the same. For example, to convert 2 3/8 to an improper fraction, multiply 2*8 = 16, then add 3 to get 19. The improper fraction is 19/8.
Convert it to an improper fraction and multiply.
You just take any denominator, (which is the second number in a fraction) and any whole number and multiply that denominator by the whole number to get an improper fraction, say you choose, the whole number 16 and the denominator 4, multiply 4 by 16 and get 64, your improper fraction will be 64/4.
