Question

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

  1. fraction numerator 7 over denominator 16 end fraction    
  2. fraction numerator 4 over denominator 7 end fraction    
  3. fraction numerator 9 over denominator 20 end fraction    
  4. fraction numerator 6 over denominator 7 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 the 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 some fractional numbers 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 6 over denominator 7 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 4 over denominator 7 end fractionfraction numerator 7 over denominator 16 end fractionand fraction numerator 6 over denominator 7 end fractionwe have to identify the fraction that cannot be replaced with fraction numerator 1 over denominator 2 end fraction.
    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 4 over denominator 7 end fraction can be rounded to fraction numerator 1 over denominator 2 end fraction
    fraction numerator 7 over denominator 16 end fraction can be rounded to fraction numerator 1 over denominator 2 end fraction
    6 over 7 cannot be rounded to fraction numerator 1 over denominator 2 end fraction because it is near to 1.

    So, 6 over 7 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 fraction numerator 1 over denominator 2 end fraction, so, 6 over 7 cannot be rounded to fraction numerator 1 over denominator 2 end fraction.
