The calculator operates with mixed numbers in feet, inches, and inch fractions and returns calculation results in the form of a mixed number reduced fraction (if any) and decimal fractions. Calculations and Converting Imperial Units to Metric Units and Vice Versa Our calculator first converts inch fractions into decimals, then converts feet into inches by multiplying the number of feet by 12 because 1 foot contains 12 inches, then makes the required arithmetic operations.

Adding, subtracting, multiplying, and dividing length values in feet and inchesīefore doing adding, subtracting, multiplying, and dividing, you need to convert all the measurements into one common unit of length. For example, 3/4 from the example above is an irreducible fraction and it cannot be further reduced. If the numerator and the denominator can both be divided only by 1, this fraction is said to be irreducible. To get the equivalent fraction with the smallest possible numerator and denominator, the greatest common factor must be determined. Sometimes the new fraction can be further reduced to get a fraction with a smaller numerator and a smaller denominator. This new fraction is called a reduced fraction. The numerator and denominator of a fraction can be divided by the same non-zero number to get an equivalent fraction. Writing down the mixed number as the integer part and the remainder over the denominator: 3 3/4.The integer part of the division result is 3.

An improper fraction can be expressed as a whole number plus a proper fraction. Its value, if positive, is always more than or equal to 1. The second fraction can be reduced to 1/6.Ī fraction is called improper if its numerator is greater than its denominator. Examples of proper fractions are 2/3 and 5/30. Converting Imperial units to metric units and vice versaĪ positive fraction is called proper if its numerator is smaller than its denominator.Adding, subtracting, multiplying, and dividing feet and inches.Converting improper fractions to mixed numbers.When performing calculations, it is necessary to tackle the following problems:
