Question

Identify the fraction that can NOT be replaced with fraction numerator 1 over denominator 2 end fraction when estimating?

  1. fraction numerator 2 over denominator 11 end fraction    
  2. fraction numerator 4 over denominator 7 end fraction    
  3. fraction numerator 9 over denominator 20 end fraction    
  4. fraction numerator 5 over denominator 11 end fraction    

Hint:

Fractions are referred to as the components of a whole in mathematics. A single object or a collection of objects might be entire. A piece or sector of any quantity is another name for the fraction. It is indicated by the sign "/," such as a/b. For instance, in the fraction 2/4, the lower part represents the denominator, and the top part the numerator.
We have given a fractional number and we have to identify the fraction that cannot be replaced with fraction numerator 1 over denominator 2 end fraction.

The correct answer is: fraction numerator 2 over denominator 11 end fraction


    In general, the whole can be any particular thing or value, and the fraction might be a portion of any quantity out of it. The top and bottom numbers of a fraction are explained by the fundamentals of fractions. Fractions are further broken down into various categories based on the characteristics of the numerator and denominator.
    As follows:
    • Proper fractions
    • Improper fractions
    • Mixed fractions
    • Like fractions
    • Unlike fractions
    • Equivalent fractions
    Estimating sums and differences of fractions to the nearest 1/2:
    • Fractions < 1/4 are rounded down to 0
    • Fractions ≥ 1/4 and ≤ 3/4 are rounded to 1/2
    • Fractions > 3/4 are rounded up to 1
    Here the fraction that we have given is fraction numerator 9 over denominator 20 end fractionfraction numerator 5 over denominator 11 end fractionfraction numerator 4 over denominator 7 end fractionand fraction numerator 2 over denominator 11 end fraction, we have to identify the fraction that cannot be replaced with 1.
    So after looking at these numbers we can round them off as follows:
    fraction numerator 9 over denominator 20 end fraction can be rounded to fraction numerator 1 over denominator 2 end fraction
    fraction numerator 5 over denominator 11 end fraction can be rounded to fraction numerator 1 over denominator 2 end fraction
    fraction numerator 4 over denominator 7 end fraction can be rounded to fraction numerator 1 over denominator 2 end fraction
    fraction numerator 2 over denominator 11 end fraction can be rounded to 0.
    So, fraction numerator 2 over denominator 11 end fraction cannot be rounded to fraction numerator 1 over denominator 2 end fraction

    The numerical numbers that make up a fraction of the whole are called fractions. A whole can be a single item or a collection of items. A fraction is represented as a/b, where a and b are the numerator and denominator, respectively. Here we were given a fractional number and we have to identify the fraction that cannot be replaced with 1/2, so, fraction numerator 2 over denominator 11 end fraction cannot be rounded to fraction numerator 1 over denominator 2 end fraction.
