Arecipe for potato salad calls for one teaspoon of vinegar for every 2 teaspoons of mayonnaise. how many teaspoons of vinegar are needed for 16 teaspoons of mayonnaise

The amount of vinegar is the amount of mayo divided by 2. therefore the answer is 8 teaspoons of vinegar.

If it were the other way around and you knew the amount of vinegar and needed to find out the amount of mayo, you would multiply the vinegar by 2

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
