Kipish [7]

The required mixed number is 3\frac{5}{6} . The calculations are attached with the solution as an image.

What is a mixed number ?

  • A bit represented with its quotient and remainder is a mixed bit. For illustration,21/3 is a mixed bit, where 2 is the quotient, 1 is the remainder.
  • So, a mixed bit is a combination of a whole number and a proper bit. A mixed bit, also called a mixed number, is a whole number and a bit together.
  • The bit is written to the right of the whole number.
  • A mixed number is formed by combining three corridor a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper bit that makes the mixed number.
