If the decimal is terminating or repeating then it can be written as a fraction. Decimal representations which are non-terminating and non-repeating cannot be expressed as a fraction.

0.675689 is a terminating decimal between the two given numbers and its equivalent fraction is 675689/1000000.

given the fraction is 1/5 you divide 1 by 5 and get .2 to turn .2 to a percentage add a 0 to the end and remove the decimal point the answer is 20%

0.91 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 91/100 which cannot be simplified. Also, the absolute value of the given fraction is less than 1. There is, therefore, no sensible way to represent it as a mixed fraction.

To convert a decimal into a fraction, place a 1 under the decimal number (to represent a fraction), move the decimal point to the right of the decimal number and add as many zeroes to the bottom number as the number of places the decimal was moved on the top number. Reduce the fraction to its lowest term. Conversion of given decimal number: .7 (place a 1 underneath to make a fraction) ,7/1 (move the decimal point to the right of the decimal number and add that many zeroes to the bottom number) 7/10 (this fraction cannot be reduced so it is the answer) Other example: conversion of .375 .375 .375/1 375/1000 (now reduce the fraction t its lowest term) 3/8

You turn the decimal into a fraction. Then you can find the equivalent fraction.

If you are trying to compare a given decimal to a given fraction, you can divide the fraction out and compare the result to the given decimal. For example, 1/2 = 1 divided by 2. = 0.5 3/4 = 3 divided by 4. = 0.75

To determine the decimal for any given fraction all you need to do is simply divide the numerator by the denominator. For this fraction (1/8) you divide 1 by 8 to get 0.125

To write something in rational form means to write it as a fraction. If you are given a negative number in the form of a fraction, it is already in rational form. If you are given a decimal and wish to turn it into a fraction, just use 10, 100, etc as the denominator. In the case of a repeating decimal there is a method but that's another question!
