What is runoff voting

okay.

Step-by-step explanation:

Runoff voting can refer to:

Two-round system, a voting system used to elect a single winner, whereby only two candidates from the first round continue to the second round, where one candidate will win.

Instant-runoff voting, an electoral system whereby voters rank the candidates in order of preference.

Contingent vote, a two-round system of instant-runoff voting.

Exhaustive ballot, a reiterative voting system, whereby rounds of voting continue (with or without elimination) until one candidate achieves a majority, also called repeated balloting.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
