An "improper" fraction is a fraction whose numerator is greater than the denominator, for example 5 / 2 . Mixed numbers are mathematical expressions made up of an integer and a fractional part, for example 2+ 1 / 2 . It is usually easier to imagine two and a half pizzas (2+ 1 / 2 ) rather than "

Converting a simple fraction to a decimal number is pretty easy once you understand how it works. You can do this with a simple column division, multiplication or even using a calculator if you prefer. Once you master the technique, you will be able to move from decimal numbers to fractions (and vice versa) with agility.

You will usually use a ruler or tape measure to make measurements in millimeters. If you don't have one, there are also methods for estimating a length in millimeters. Similarly, if you have a measurement expressed in another unit of length, you can convert that measurement to the equivalent value in millimeters.

In the metric system the gram is used to measure the weight of small objects or small quantities while the kilogram is reserved to indicate the mass of very heavy elements. A kilogram is made up of 1,000 grams. This equivalence indicates that, to convert a weight expressed in grams into kilograms, it is simply necessary divide the number of grams by 1,000 .

In mathematics, for factorization we intend to find the numbers or expressions that by multiplying each other give a certain number or equation. Factoring is a useful skill to learn in solving algebraic problems; when dealing with second degree equations or other types of polynomials, the ability to factorize becomes almost essential.

Squaring fractions is one of the simplest things you can do. The procedure is very similar to the one used with whole numbers, because you just need to multiply both the numerator and the denominator by itself. There are cases in which it is better to simplify the fraction before raising it to a power, to make operations easier.

Factoring into prime numbers allows you to decompose a number into its basic elements. If you don't like working with large numbers, like 5,733, you can learn to represent them in a simpler way, for example: 3 x 3 x 7 x 7 x 13. This type of process is indispensable in cryptography or in the techniques used to guarantee information security.

Calculating the inverse of a quadratic function is simple: it is sufficient to make the equation explicit with respect to x and replace y with x in the resulting expression. Finding the inverse of a quadratic function is very misleading, especially since Quadratic functions are not one-to-one functions, except for an appropriate bounded domain.
