Why is 100 used as the denominator when changing 0.25 to as fraction as 25 over 100?

The number 0.25 has two digits after the decimal place, so the denominator, in the first instance, must have two zeros after the 1. The reason for saying "in the first instance" is that 25/100 can be simplified to 1/4 and many people will change 0.25 to 1/4 without going through the division by 100.

∙ 8y agoThat's because of the two digits after the decimal point. For one digit, you use 10 as the denominator; for two digits, you use 100, for three digits, you use 1000, etc.

How are divisors and denominators alike?
A fraction represents a decimal number in the form of one number over (or divided by) another. To convert a fraction to a decimal the numerator is divided by the denominator; the denominator is the divisor in this case. A division can be written with the divide symbol (÷) or a solidus (or slash /). The latter is used by most (if not all) computer languages. The solidus is also used to separate the numerator from the denominator of a fraction. The divisor of a division and the denominator of a fraction both occur on the right of the slash in the same place; thus they are the same thing.
What is proper fraction and improper fraction?
Proper Fractions:a fraction in which the numerator is smaller than the denominator such as:6/9 or 4/7...improper fraction:a fraction in which the numerator is bigger than the denominator such as: 18/4 or 97/3. Improper fractions are normally used when converting fractions.
What is one technique used to convert a measurement in one unit into a different unit with out changing the value of the measurement?
Multiply the original quantity by a conversion factor, a fraction containing the desired unit in the numerator and the original unit in the denominator so that the fraction is equal to one.
How can the GCF be used to write a fraction in simplest form?
Find the GCF of the numerator and the denominator and divide them both by it. If the GCf is 1, the fraction is in its simplest form.
Which is used to represent how part relate to the whole?
It is the numerator of a fraction which is above the denominator.

Finding the lowest common denominator
How is a Greatest common Factor used to find the simplest form of a fraction?
If the GCF of the numerator and the denominator is 1, the fraction is in its simplest form.
How do you simplify the fraction?
first multiply the denominator to the mixed number. then,when you got the product, add the product to the numerator. then,when you got the sum, copy the sum as numerator and the denominator was the last denominator you used.
What is the term used to describe the portion of the fraction occupied by the 1 in the fraction below?
The top number of a fraction is called the numerator. The bottom number of a fraction is called the denominator.
When is a denominator used?
A denominator is the bottom number in a fraction. It is also the same thing as the divisor in a division problem. For example: in the fraction 1/2, 2 is the denominator; the mathematical expression of the fraction 1/2 is the same as the mathematical expression of 1 divided by 2. It can also be expressed in ratio form (i.e. 1:2).
When dividing fractions is a reciprocal used by multiplying?
Yes. One method for dividing fractions is to multiply the numerator fraction by the reciprocal of the denominator fraction.
What is used to reduce a fraction to simplest form?
To put a fraction in its simplest form, find the GCF of the numerator and denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
