Final answer:
To estimate 89 as a fraction, one could approximate it to 90 which is like ¾ (expressed as 9/10 in simplest form). This is not exact but can be used for estimation. The process relates to understanding conversions between numbers, fractions, and percentages.
Step-by-step explanation:
To estimate 89 as a fraction, we usually look for a number close to it that has a simple fractional form. Since the student's question seems to involve rounding or estimation, the number 89 does not directly correspond to a common fraction. However, if we were to estimate, we might say that 89 is close to 90, which is ⅔ (90/100). This could be further simplified to ¾ (9/10). This is just an estimation, as 89 does not equal 90, but it can be used for approximation purposes.
The calculation provided in the question references various statistical information, such as confidence intervals and percentiles, but these are not directly related to the process of estimating 89 to a fraction. We see the process of converting fractions to decimals and percentages demonstrated with the number 833, which is estimated as 833 over 1000, or 83.3%.
