I guess you mean a mixed fraction, such as 5 2/3, which basically means 5 + 2/3. To get the multiplicative inverse, you must first convert the fraction to an improper fraction (in this example, 17/3). Then, to get the multiplicative inverse, you exchange top and bottom (in this example, 3/17).
Note that to do the conversion, I multiplied 5 x 3, and added 2 to the result. This number (17) goes into the numerator (top); the denominator (bottom) doesn't change.

when you flip a fraction or whole number upside down. a/b = b/a.
You simply multiply the whole number by the denominator. A whole number divided by a fraction is the whole number times the inverse of the fraction. For example, 8 divided by 1/4 is 8 times 4 = 32.
You can make any whole number into a fraction by putting it over 1.
To divide a whole number by a fraction, you can rewrite the fraction as a whole number by multiplying the denominator by the whole number. Then, divide the resulting whole number by the numerator of the fraction. This process is equivalent to multiplying the whole number by the reciprocal of the fraction.
No. A rational number is one that may be represented as a simple multiple, or a division. Such as one times seven, or three times seven; OR one divided by seven, or three divided by seven. Or similar.A rational number, if a fraction, when multiplied by the divisor of the fraction, will give a simple whole number. e.g. 7/5, when multiplied by 5 becomes the whole number 7.An irrational number is one that cannot be formed by a simple ratio, or a simple division. e and pi are a couple of common irrational numbers. [irrational demonstrates where the name comes from.]No number can be found which will convert them, by multiplication, into a whole number.
