Consider this example: Sarah says, "Out of every 10 apples I gather, 1 is rotten." The rotten-to-gathered arrangement is (1 apple) / (10 apples) = 0.1 = 10%, which is a dimensionless quantity.
Plane angles – An bend is abstinent as the arrangement of the breadth of a circle's arc subtended by an bend whose acme is the centre of the amphitheater to some added length. The ratio—i.e., breadth disconnected by length—is dimensionless. When application radians as the unit, the breadth that is compared is the breadth of the ambit of the circle. When application amount as the units, the arc's breadth is compared to 1/360 of the ambit of the circle.
In the case of the dimensionless abundance ПЂ, getting the arrangement of a circle's ambit to its diameter, the amount would be connected behindhand of what assemblage is acclimated to admeasurement a circle's ambit and bore (e.g., centimetres, miles, light-years, etc.), as continued as the aforementioned assemblage is acclimated for both.
