The following by the other person is WRONG!! "(11)(-10)=-110"

Plus, converting the decimals to fractions to get to the answer is, in this author's opinion, OVERKILL!

The reciprocal of a number, when expressed as a fraction, is obtained by SWITCHING the numerator and the denominator. In other words, the
denominator and the numerator of the original fraction become the NEW numerator and NEW denominator, respectively, of the reciprocal.

I don't know why you say this, "All other questions have fractions but this one dosent....", because -12.1/-0.11 is a FRACTION!

So, the RECIPROCAL of {{{(- 12.1)/(- 0.11)}}} is merely {{{(- 0.11)/(- 12.1)}}} = {{{0.11/12.1}}} = {{{1.1/121}}} = {{{highlight(0.1/11)}}}, or {{{1/10}}} ÷ {{{11/1}}} = {{{(1/10) * (1/11)}}} = {{{highlight(1/110)}}}</font></font></font></b></pre>
