Definition: A Percent is a number or ratio expressed as a fraction of 100, in other words Percent is a fraction of denominator 100. Percent is denoted by the symbol %. ‘Per’ ‘cent’ means out of 100. The […]
Read More →What is Ordinate Ordinate is the value of the Y coordinate on a coordinate plane. or Ordinate is the value of the Y axis on a coordinate plane. In a coordinate plane, the Ordinate is the Y coordinate of a point. The Vertical line is called the Y axis. The distance of a point from the X axis is called its Y coordinate or Ordinate. The Ordinate always comes […]
