A more complicated way handling numbers derived from fractions in the ordinary way (as 'Double'), but displaying them as fractions with a limited set of allowed denominators will not pay for the trouble and is only supported by LibreOffice. Ways to create such a representation and to calculate with it may be discussed if a specific question is asked. As a makeshift you may keep a fraction as a text showing the standard notation (like "28/30"). If you need to know the numerator and the denominator separately you should use two (adjacent) cells to keep them. Calc doesn't offer a specific way to keep stored fractions and to calculate with them. Any (positive) rational number is represented by an infinite set of equivalent fractions. 4- A fraction in the narrowest sense is a pair of natural numbers, the numerator and the denominator, commonly written as numerator/deniminator or in a similar way. The results of =28/30 and of =14/15 are therefore identical. Anyway a calculated numeric result does not contain information about the expression it was derived from. Technically spoken they are represented as 'Double' regarding the standard IEEE 754. They are neither fractions nor "decimal numbers" or any different kind of (more or less) standardised ways of writing numbers. This makes troubleshooting much easier and systematic if you find you've made a mistake or want to walk through it a second time to verify what you've done (as you definitely should!).-3- Results of numeric calculations are always simply numbers. Of course there are many shortcuts you could take or even different approaches altogether, but I like to parse a problem like this down stepwise in a way that shows what you are doing and facilitates keeping track of units. Using the values (and associated units) given in your problem: multiply the (unitless) fraction found in (3) by the total glucose calculated in (1).calculate the fraction of oxygen in glucose.As suggested in the comments, keep track of the units! If your answer doesn’t make physical sense, you made a mistake.Ī thorough approach to this problem is to:
