-0.2
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.
turn the positive number into its recipricol and the put the number of the negative number on the top
Swap the denominator and numerator eg if you have 2/5 the reciprocal of it is 5/2
Reciprocals are numbers that when multiplied together will equal one. 4/5 and 5/4 are reciprocal.
Zero doesn't have a negative reciprocal. Zero doesn't have a reciprocal at all. It's zero. Zilch, nix, zip, nada, diddly-squat.
The reciprocal of -19 is -1/19
When you have a negative exponent (for example 3^-3) you could make the recipricol of the number. So, this would be 1/3^3. Then all that you would have to do is solve for the exponent ( so in this case the answer would be 1/27)
The reciprocal of 7654321 is: 1 over 7654321 or 1/7654321
Flip it. The reciprocal of 3/4 is 4/3
You don't multiply by the second number, you multiply by the recipricol. For example, 5/8 divided by 3/5... you multiply 5/8 by 5/3. Which would give you 25/24ths, or 1 and 1/24.
Put a 1 over it. The reciprocal of 3 is 1/3
