a recipricol of a fraction is the fraction flipped over, with the numerator in the denominators place and vice versa.
-0.1 or in fraction form it is -1/10 recipricol just means to flip the fraction. since -10 is the same as -10/1
When you multiply a fraction by its recipricol you will always end with the answer of 1.EX.4/6 x 6/4 = 14x6=246x4=2424 divided by 24 = 1
-0.2
The definition of an multipilicative inverse is a number that's times by the known number to attain a product of one. To find the multiplicative inverse is the same thing as the recipricol of the number. To find the multiplicitive inverse or recipricol of a number, first turn the number into a fraction, then switch the numerator and denominator around. The result is your multiplicitive inverse.
Assuming you are asking about a reciprocal rather than a recipricol(!), the answer is one divided by the number.So, for example, reciprocal of -3 = 1/(-3) = -1/3.
The reciprocal of -19 is -1/19
The reciprocal of 7654321 is: 1 over 7654321 or 1/7654321
Flip it. The reciprocal of 3/4 is 4/3
Put a 1 over it. The reciprocal of 3 is 1/3
you switch the second fraction around ( multiply by the reciprocal ) because it is way easier than trying to actually divide the fraction by dividing, you get the same answer. but we multiply by the recipricol because multiplying fractions is simpler. example.... 4/6 divided by 8/5 you then get 4/6 * 5/8 = 5/12
the blank of 7 = 1/7 blank=recipricol
