You Look at the angle the problem gives you
To find major arcs in a circle, first identify the endpoints of the arc on the circumference. Measure the angle subtended by the endpoints at the center of the circle; if the angle is greater than 180 degrees, the arc is a major arc. Alternatively, you can calculate the minor arc (the shorter arc between the two points) and subtract its length from the total circumference to find the length of the major arc. Major arcs are typically labeled with three points, including the endpoints and a point on the arc itself.
To find the measure of a major arc in a circle, first determine the measure of the corresponding minor arc, which is the smaller arc connecting the same two endpoints. The measure of the major arc is then calculated by subtracting the measure of the minor arc from 360 degrees. For example, if the minor arc measures 120 degrees, the major arc would measure 360 - 120 = 240 degrees.
A central angle splits a circle into two distinct arcs: a major arc and a minor arc. The minor arc is the smaller arc that lies between the two points on the circle defined by the angle, while the major arc is the larger arc that encompasses the rest of the circle. The measure of the central angle is equal to the measure of the minor arc it subtends.
The arc formed where a central angle intersects the circle is called a "major arc" or "minor arc," depending on the size of the angle. The minor arc is the shorter path between the two points where the angle intersects the circle, while the major arc is the longer path. The measure of the arc in degrees is equal to the measure of the central angle that subtends it.

Major arc is the longer of two arcs.

the fraction of the circle covered by the arc
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
It is simply greater than 180 degrees but less than 360 degrees
Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
A circle subtends 360° . Therefore. if the angle subtended at the centre of a circle by an arc is greater than 180° then this is the major arc. By comparison, the minor arc will subtend an angle less than 180°
