How do you approximate a fraction to the nearest whole?

To round a fraction to the nearest whole number, compare the fraction to 1/2. If the numerator of a fraction is more than half its denominator, the fraction is more than 1/2. If the numerator is less than half the denominator, the fraction is less than 1/2.

When estimating a mixed fraction What steps do you follow?

First step: Write the whole number and the mixed number as improper fractions.

1. Second step: Write the reciprocal of the divisor, 2/5, and multiply.
2. Third step: Simplify, if possible.
3. Fourth step: Perform the simple multiplication of the numerators and the denominators.

Which fraction is a good approximation?

John Heidemann at the Information Sciences Institute at USC has a list of all the best rational approximations (of the first kind) of pi with denominators up through about 50 million. The numbers 3/1, 13/4, 16/5, 19/6, and 22/7 are the first few fractions on this list. 13/4 is a little closer to pi than 3 is.

How do you find the approximate value of a fraction?

When trying to calculate (approximate) a fraction ‘p/q’, add a value to the denominator and a corresponding value to the numerator before calculating (approximating). Case 1: 762 is 12 above 750, so I will subtract 12 from the denominator. Keeping the factor of 2.5 in mind, I will subtract 30 from the numerator.

Who created continued fractions?

The Dutch mathematician and astronomer Christiaan Huygens (1629-1695) was the first to demonstrate a practical application of continued fractions. [6][5] He wrote a paper explaining how to use the convergents of a continued fraction to find the best rational approximations for gear ratios.
