1.25 can be written as a fraction in a couple of different ways. The first way to write 1.25 as a fraction is to divide the decimal number by 10 to get the fraction 125/1000. The second way to write 1.25 as a fraction is to divide the decimal number by 100 to get the fraction 12.5/100.

Introduction
In mathematics, a fraction is a number that represents a part of a whole. It is written as a pair of numbers, with the fraction bar between them, such as 1/4, 2/3, 3/8, 5/12, etc. The number on top of the fraction bar is called the numerator, and the number on the bottom is called the denominator. The denominator tells us how many parts the whole is divided into, and the numerator tells us how many of those parts we have. So in the fraction 3/8, the numerator is 3, and the denominator is 8. This means that we have 3 out of 8 parts, or that our whole is divided into 8 parts and we have 3 of those parts.
What is 1.25 as a Fraction?
1.25 can be written as 1 1/4 or as a fraction it would be 5/4. When written as a fraction, the number before the slash is the numerator and the number after the slash is the denominator. The numerator is the number of parts you have, and the denominator is the number of equal parts the whole is divided into.
Decimals, Fractions, and Percents
Decimals, fractions, and percents are all ways of representing numbers. In general, decimals are used for calculations, fractions are used for measurements, and percents are used to describe proportional relationships.
1.25 as a fraction is 5/4. This can be simplified to 1 1/4 or 1.25. Decimals and fractions both represent numbers, but they have different implications. A decimal is a number that represents a portion of something whole, while a fraction is a number that represents a part of a whole or a part of a group. In other words, decimals imply division while fractions imply parts of a whole.
Percents are another way to represent proportions. They are often used to express how one quantity is related to another quantity as a percentage. For example, if you earn $10 per hour, you could say that you make 10% of $100 per hour ($10/$100 = 0.10 = 10%).
Terminating and Repeating Decimals
When a decimal such as 1.25 terminates, this means that there is a definite end to the numbers after the decimal point. In other words, if you were to divide 1.25 by 10, 100, 1000, or any other number, you would always get a number that terminates after two digits past the decimal point. So, 1.25/10=0.125, 1.25/100=0.0125, and 1/1000=0.00125.
A terminating decimal is also called a rational number because it can be expressed as a ratio of two integers (in this case 1 and 25). All fractions can be expressed as terminating decimals; for example 3/4=0.75 and 2/5=0.40
Converting a Decimal to a Fraction
To convert a decimal to a fraction, we place the decimal number over its place value.
For example, 1.25 is equal to 1 ÷ 10 + 2 ÷ 100 + 5 ÷ 1000, so its fractional form is 1/10 + 2/100 + 5/1000.
To simplify this fraction, we first find the greatest common factor of all the numbers in the numerator and denominator. In this case, the greatest common factor is 5.
We divide both the numerator and denominator by 5 to get 1/2 + 1/20 + 1/200.
The final step is to reduce this fraction by dividing both the numerator and denominator by their greatest common factor, which in this case is 1. Therefore, 1.25 as a simplified fraction is 1/2 + 1/20 + 1/200, or 6/24.
Conclusion
To recap, 1.25 as a fraction is 5/4. This can be written as a decimal by dividing the numerator by the denominator which would give you 1.25. If you need to simplify this fraction, you can do so by dividing both the numerator and denominator by the same number until you can’t anymore. In this case, 5 goes into 5 once and 4 goes into 20 five times so the simplified version of 1.25 as a fraction is 5/4 or 1 1/4.
