Divide the numerator by the denominator, and the largest whole number becomes the integer. The leftover remains as the numerator of the fraction.
Examples
15/7 = 2 plus remainder 1 = 2 1/7
32/30 = 1 plus remainder 2 = 1 2/30 = 1 1/15
By changing the mixed number into an improper fraction.
First you would want to change the mixed number to an improper fraction. Then you can subtract
If you are using the same number, then the improper fraction and mixed number are equal.
Improper Fraction.
Changing an improper fraction to a mixed number - simply divide the denominator number into the numerator. For example take the fraction 37/16. 16 divides into 37 twice with 5 remainder. So the proper fraction would be 2 & 5/16.Changing from a mixed number to an improper fraction - multiply the whole number by the denominator, then add the numerator. Using the above example of 2 & 5/16, this would be 16x2 then add 5 to give 37/16.
43 is an integer, not an improper fraction nor a mixed number.
A mixed number can be changed into an improper fraction
Yes, it can. In fact every mixed number has an equivalent improper fraction.
A mixed number is a whole number and a fraction. It can be rewritten as an improper fraction.
Convert the mixed number into an improper fraction then divide the fraction and improper fraction as normal (invert the divisor and multiply) and simplify the result (including converting any improper fraction into a mixed number)
Improper fraction is 23/6 and mixed number is 3 5/6
The mixed number ab/c is equivalent to the improper fraction (a*c+b)/c
