Long multiplication means you're doing multiplication by hand. The traditional method, or Standard Algorithm, involves multiplying numbers and lining up results according to place value. These are the steps to do long multiplication by hand: Critical clearances, motorcycle compatibility and stability, load-bearing capacity, speed rating, radial vs. non-radial, pattern and tread compound requirements, inflation recommendations, and front-to-rear tire matching will all vary with tire selection.

thing as 7/10. Now we can add these two. What is 70 plus 5? 70 plus 5 is 75. And our denominator is Some manufacturers put the speed rating at the end of the size and do not indicate if the tire is tubeless or not. In that case the size would look like this 120/70-17Z. 120 In engineering, fractions are widely used to describe the size of components such as pipes and bolts. The most common fractional and decimal equivalents are listed below. 64 thThis process can be used for any number of fractions. Just multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions (not including its own respective denominator) in the problem. EX: When a is a fraction, this essentially involves exchanging the position of the numerator and the denominator. The reciprocal of the fraction 3 What do these terms alphabetical, metric and std inch mean? They are explained in a section below. The sizes in the above chart do not go as large as modern sizes (180/55 or 240/40) because new bikes are not made to use the Inch Format. In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction of 3 The Section Width is the width of the tire measured from the middle of the side walls (above the bead, below the tread).

Insert a decimal point in the product so it has the same number of decimal places equal to the total from step 1. The Aspect Ratio is the tire section height divided by the section width (not tread width), multiplied by 100. The section height is measured at the center of the tire crown. The tread width is usually greater than the section width. The section width is measured from the middle side walls (above the bead, below the tread). It is It is often easier to work with simplified fractions. As such, fraction solutions are commonly expressed in their simplified forms. 220

The Speed Rating is explained in detail here. For our example a speed rating of Z means this tire is rated for speeds exceeding 149mph.

The speed rating is explained in detail below, but in our example, a speed rating of H means this tire is rated for speeds not to exceed 130mph or 210kph. The Ply Rating is a descriptive abbreviation. It refers to the number of plys (layers) that make up the tire. For more on descriptive abbreviations, see sections below. For specific strength of the different ply tires, refer the tire manufacturers literature. Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top numberFraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to the addition section as well as the equations below for clarification. a Not all manufacturers will add the TL to indicate that it is tubeless. It was used more when they were not as common as today. Inch Size Format An alternative method for finding a common denominator is to determine the least common multiple (LCM) for the denominators, then add or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely to result in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The least common multiple is the first shared multiple of these three numbers. Multiples of 2: 2, 4, 6, 8 10, 12 The vast majority of tires manufactured and sold today come with metric sizing. The tire size we will use for our example is a 120/70ZR-17TL. It can also be written as 120/70Zx17TL or 120/70ZR17TL. Also, inch size format tires are all bias type. They do not come in radial. The size will will use for this example is 4.60x17H 4PR. You may also see this written as 4.60H-17 4PR. 4.60

Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand. as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.Long multiplication with decimals using the standard algorithm has a few simple additional rules to follow.
