artcher [175]

Answer:

A quarter $(\dfrac{1}{4})$ of one lap of the track.

Step-by-step explanation:

Three students ran ran a relay and took turns running equal parts of the track.

The race was three-fourths of a lap long.

Let the length of one lap of the track=x

The length of the race $=\frac{3}{4}x$

Since each of the students ran equal part,

Length run by each student

$=\dfrac{3}{4}x \div 3\\=\dfrac{3}{4}x X \dfrac{1}{3}\\=\dfrac{1}{4}x$

Therefore, each student ran a quarter $(\dfrac{1}{4})$ of one lap of the track.
