If the ratio of a new quantity to an old quantity can be expressed as an improper fraction, then the new quantity is greater than the old quantity. Applying this ratio to the old quantity is known as increasing the old quantity in a given ratio.
How do you write 1 to 2 as a ratio?

How do you convert a part to part ratio to fractions?
To convert a part-to-part ratio to fractions: Add the ratio terms to get the whole. Use this as the denominator. 1 : 2 => 1 + 2 = 3. Convert the ratio into fractions. Each ratio term becomes a numerator in a fraction. 1 : 2 => 1/3, 2/3.
What is the part-to-part ratio of 1 2?
Each ratio term becomes a numerator in a fraction. Therefore, in the part-to-part ratio 1 : 2, 1 is 1/3 of the whole and 2 is 2/3 of the whole. To reduce a ratio to lowest terms in whole numbers see our Ratio Simplifier. To simplify a fraction into a reduced fraction or mixed number use our Simplifying Fractions Calculator .

What is Ratio?
A ratio is a quantitative relationship between two numbers that describe how many times one value can contain another. Applications of ratios are fairly ubiquitous, and the concept of ratios is quite intuitive. This could likely be demonstrated by giving a child half as many cookies as his sister. While the child may not be able to voice the injustice using ratios, the raucous protestations that would most likely ensue should make it immediately obvious that he is well aware he has received 1:2 as many cookies as his sister, conceptually, if not mathematically.
What is aspect ratio?
The aspect ratio is the ratio of a geometric shape's sizes in different dimensions. In the case of a rectangle, the aspect ratio is that of its width to its height. Although aspect ratios are widely used in applications such as tire sizing, paper sizing, and standard photographic print sizes, some of the most frequent uses of aspect ratios involve computer screen dimensions, mobile phone screens, and video sizes. As such, below is a list of typical computer screen/video resolutions and aspect ratios.

What is the size of a full frame camera?
As mentioned, professional, full-frame digital cameras still conform to the 3:2 size based on the 35mm film frame. However, advanced photo system type-C (APS-C) crop sensors from entry-level DSLRs also use the same aspect ratio despite being smaller than their full-frame counterparts. Canon’s 22.20mm x 14.80mm and Nikon’s 23.6 (or 23.7mm x 15.60mm) APS-C sensors are both smaller than the full frame 36 x 24 size. Nonetheless, they still have a 3:2 aspect ratio.
What is aspect ratio?
Photo by RawPixel. In simplest terms, aspect ratio is the relationship between the width and the height of an image. The reason it's so essential is because it influences how you compose your photograph and how big it’s going to be.
Why is panorama important?
Due to its considerable width, this format is considered panoramic. In other words, it captures a wider area than other aspect ratios. That’s why it’s the format a lot of landscape photographers prefer. It’s also popular among filmmakers because of the cinematic look it offers. In the late 2000s, it surpassed the 4:3 video format in popularity and is now the standard for television and online content.
How to maintain quality of photos?
To maintain quality, the ratio of your image size should never exceed your camera sensor's. For instance, if you’re using a micro four-thirds camera, stick to 4:3 or 1:1. If you try 3:2 or even 16:9, you’ll be forced to crop a considerable portion of your photo. Consequently, you’ll end up with a photo with poor quality.
