A representative fraction is the ratio of the unit of measurement on a map to its equivalent measurement on actual ground. The ratio of the Earth's size to the generating globe's size is called the nominal scale (= principal scale = representative fraction).

Translate Representative fraction in English online and download now our free translator to use any time at no charge. To calculate this, we take the ratio, convert it to a fraction, and then perform the arithmetic: 3:2 = 3/2. They can also be written as "1 to 2" or as a fraction ½. Or we could say it's 2/5, the fraction 2/5, which would sometimes be read as 2 to 5. Once inserted, you can also double click the RF to change even more properties. Only divide the numerators and denominators if they can be divided exactly to produce a whole number. Mole fraction is useful when two reactive components are mixed together, as the ratio of the two components is known if the mole fraction of each is known. Therefore 1 mile = 1760*3*12 = 63360 inches. The scale of a map or chart expressed as a fraction or ratio that relates unit distance on the map to distance measured in the same unit on the ground.

Therefore, RF scale = map distance Ground distance-That is- the top number (numerator) represents the map distance on the ground and is usually more than 1. Many maps state the nominal scale and may even display a bar scale (sometimes merely called a 'scale') to represent it. ÷ 4 ___4 20 = __1 5 ÷ 4 1/4 of a mile = 63,360/4 = 15840 inches. Next, explain how your fraction describes the set: Of a whole: Almost always, fractions are written as some number of a whole group.
