Fractions and percentages are both ways to represent a part of a whole as 13/16. A fraction consists of a numerator 13 (the top part) and a denominator 16 (the bottom part), with the numerator representing the part and the denominator representing the whole. In contrast, a percentage 81.25 represents a part out of 100. Converting between fractions and percentages can help us better understand and compare different quantities or proportions.

Fractions are commonly used in everyday life. If you are splitting a bill or trying to score a test, you will often describe the problem using fractions. Sometimes, you may want to express the fraction as a percentage.

Engineers apply the knowledge of math & science to design and manufacture maintainable systems used to solve specific problems. AskEngineers is a forum for questions about the technologies, standards, and processes used to design & build these systems, as well as for questions about the engineering profession and its many disciplines.

The issue is where am I supposed to find a M3x14 where only 5mm of it is threaded? I understand these are shoulder bolts but I cant really even find 14mm M3 bolts let alone ones which match exactly these.

They used a M3x14mm bolt with some sort of flat head with a hex driver. Interestingly it is partially threaded. About 9mm of it is smooth and 5mm of it is threaded. And I cant look close enough but there is possibly somewhat of a ring inbetweeen.

Another example could be in measuring ingredients for a recipe. If you know that you need 1/2 (1 / 2) of a cup of an ingredient, converting this fraction to a percentage (50%) can help you visualize how much you need relative to a full cup.

Remember, a percentage is any number out of 100. If we can balance 13 / 16 with a new denominator of 100, we can find the percentage of that fraction!

I cant post a picture but if you look up "Bambu X1C Hotend Screws" you will see some images of the screw as well as some images showing where they go.

Keep in mind that you can also reverse these steps and still arrive at the correct solution. If you multiply the numerator (13) by 100 first and then divide the result by the denominator (16), you will still get the correct percentage (81.25%).

My 3D printer has two bolts used to help securely swap out nozzles. Basically each nozzle assembly has 2 holes that are perfectly aligned with another part on the nozzle.

In this example, we have converted the fraction 13 / 16 into a percentage: 81.25%. This means that the fraction 13 / 16 is equivalent to 81.25 parts out of 100. It can be useful to know both the fraction and percentage forms when solving problems or interpreting data.

13/16 = 81.25% as a percentage & 0.81 as a decimal. We teach our students all three as they are each part of understanding fraction conversions. To solve more coversions, we encourage you to check out our introduction to percentage page for a little recap of what percentage is. You can also learn about fractions in our fractions section of the website. Sometimes, you may want to express a fraction in the form of a percentage, or vice-versa. This page will cover the former case. Luckily for us, this problem only requires a bit of multiplication and division. We recommend that you use a calculator, but solving these problems by hand or in your head is possible too! Here's how we discovered that 13 / 16 = 81.25% :

Fractions and percentages are used in many real-world situations. For example, when calculating discounts on products, understanding both the fraction and percentage can help you quickly determine how much you will save. If a store offers a discount of 1/4 (1 / 4) off the original price, you can convert this fraction to a percentage (25%) to better understand the savings.

An "bonus" question is that the end of it has a bit of blue (what I am assuming is thread lock). When I looked up options here most cap out at 150-230C and while much higher temperature resistant ones do exist they seem suited for automotive and mention bolt sizes much larger than my M3. Realize this may not be strictly a mech e question.

Now the hole for a hex driver is already starting to strip and I am a month or two in. I noticed when I over tightened them with a driver and couldn't get them out with a ball end hex and had to get out a flat end hex. They sell replacement kits but I am very much interested in seeing if I cant buy a bunch of these so I can replace this somewhat frequently. I might also be able to find one made in a higher quality or with a deeper hex groove.

When converting fractions to percentages, it's essential to remember that percentages always have a denominator of 100. To convert a fraction like 13 / 16 into a percentage, you can follow these steps:
