The factors of 28 are 1, 2, 4, 7, 14 and 28. To get the factors, the number 28 must be divided by whole numbers starting from 1, and the quotient must also be a whole number. If this is the case, the quotient and the divisor are considered factors for the number in question.Continue Reading
The number 28 may be presented as a product of 1 and 28, which are two of the factors. It may also be calculated as a product of the following number combinations: 2 and 14, and 4 and 7.
A convenient way to determine the factors of any number is to start with the number 1. The most basic pair of factors of any number is the number 1 and the number itself, since any number multiplied by one is equal to itself. After this, divide the number by two and check if the quotient is a whole number. If it is, include this pair of divisor and quotient as factors of the number. Continue with number 3 and succeeding numbers until the number pairs become as close as possible. All of the whole number pairs generated using this method are the factors of the given number.Learn more about Fractions & Percentages
The fraction 11/12 is converted to the decimal 0.916666, which can be rounded to 0.9167. Students can find the answer either by performing a long division of 11 by 12 or by using certain facts, such as the fact that 1/12 is equal to the decimal 0.083333 in which 3 is a repeating digit.Full Answer >
Decimals are most often used when referring to money. If someone has $3.42, for example, he has three whole dollars and 42/100 of a dollar. Most people find it easier to compare two decimals than two fractions.Full Answer >
The expression pi in MATLAB returns the floating point number closest in value to the fundamental constant pi, which is defined as the ratio of the circumference of the circle to its diameter. Note that the MATLAB constant pi is not exactly equal to the fundamental constant pi.Full Answer >
When rounding decimals, the number value of the last retained decimal is increased by 1 if the number in the next decimal place is 5 or greater. If the next decimal is less than 5, the number value of the last retained decimal simply remains the same.Full Answer >
