(mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; the multiplicative inverse of 7 is 1/7

The reciprocal of a number is the quotient obtained by dividing one by the number. Thus the reciprocal of 8 is 1/8. Applied to fractions the above operation is carried out by simply inverting the fraction. Thus the reciprocal of 3/4 is 4/3 or 1-1/3.

As if math wasn't hard enough without this, huh?

I hope this was of some help to you. Good luck,

Bill

A mixed number is a number composed of an integer (whole) number and a proper fraction, one that has a numerator less than the denominator. Example 2 1/3 =2+ 1/3. 2 is the integer part, and 1/3 is the proper fraction part.

Certain fractions can be simplified further because the numerator and denominator share a (common) factor. By cancelling the common factor in the numerator with the factor in the denominator,

one gets a fraction with smaller numerator and denominator.

For example the percentage you provide 0.15% can be converted to 15/10000.

Since 15 and 1000 are both multiples of 5, the number 5 is a common factor in both. 15=5*3, and 10000=5*2000

Cancel the two 5 (simplifying by 5) in numerator and denominator leaves 3/2000. Thus

0.15%= 0.15/100=0.0015=3/200

I hope that this makes sense to you.

The opposite of any number (be it integer, rational, or real) is the same number preceded by the negative sign.

Example : the opposite of a is -a (read it a negative a)

opposite of (-b) is -(-b)=b

A rational number is a number that can be written as a fraction. You should note that the set of rational numbers contains the set of all integers .

The opposite of 15/37 is -(15/37) which is equivalent to (-15)/37 and 15/(-37).

Example : the opposite of a is -a (read it a negative a)

opposite of (-b) is -(-b)=b

A rational number is a number that can be written as a fraction. You should note that the set of rational numbers contains the set of all integers .

The opposite of 15/37 is -(15/37) which is equivalent to (-15)/37 and 15/(-37).

Convert the mixed numbers into improper fractions, and multiply the improper fractions. Do not forget to reduce the product to its simplest form.

Convert each mixed number (what you call mixed fraction) to an improper fraction, then multiply the two numerators and multiply the two denominators. Reduce the resulting fraction to its simplest form

Example

(2 1/3)*(1 5/7)=?

Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3

Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7

(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)

The 7's in the numerator and denominator cancel one another leaving

12/3=4

**(2 1/3)*(1 5/7)=4**

Not all products of mixed numbers will give a simple result as this one. More likely they will not.

Example

(2 1/3)*(1 5/7)=?

Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3

Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7

(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)

The 7's in the numerator and denominator cancel one another leaving

12/3=4

The product of any number and a positive fraction less than one is always less than the number. If both factors are less than one then the product is less than either factor.

Probably the simplest is to convert both numbers to improper fractions then divide.

Some calculators can work with fractions. With one of those, simply enter the first mixed number, then divide by the other.
