1 2 __ 1 • • closer Each numerator is equal to about half the denominator, so the fractions are close. 1 2 __ close to 1. Each numerator is approximately equal to the denominator, so the fractions are close to 1. close to 0. Each numerator is much less than half the denominator, so the fractions are close to 0. 1 5 __ 2 11 __ 2 15 __ 5 11 __ 4 7 __ 9 20 __ 9 10 __ 16 19 __ 6 7 __ 1 2 __

An estimate (or an educated guess) can be very helpful when it comes to hacking. If you’re trying to calculate specific ratios without the data or time to get an accurate answer, a good estimate will get you on the right track. However, there is a big difference between making plans and guessing. If you want to maximize your chances of accuracy, you need to take a close look at your data.

To approximate a fraction using math, start by simplifying the fraction to the lowest possible denominator. Then look at the fraction and round it to the nearest fraction you are comfortable working with. This could be ¼, ⅓, ½, ¾, or even 1. If possible, rounding to the nearest half or determining whether the fraction is close to the number may be helpful. it’s easy to simplify. If you are going to use fractions in an equation, try to make them close to a number with the same denominator. If you want to learn more, like how to evaluate fractions visually, keep reading!
