What is the difference between 1 2 and 50%?
1/2 is the same number as 0.5, so (1/2)% is the same as 0.5%. “Percent” means “per 100”, so 50% = 50/100 = 1/2. (1/2)% = (1/2)/100 = 1/200. In other words, 50% is the same as 1/2, but is not the same as (1/2)%.
What does 1/2 mean as a number?

As long as the denominators are the same, the fraction with the greater numerator is the greater fraction, as it contains more parts of the whole. The fraction with the lesser numerator is the lesser fraction as it contains fewer parts of the whole.
What is 1/2 in a whole number?
2 Answers By Expert Tutors
In the same way, 1/2 is never equal to a whole number. It is equal to 0.5, which has a decimal but not a fraction. You could multiply by 0.5 the same way you multiply by 5, except that you might have at least one extra decimal place in the answer.
How do you calculate a 2 1 ratio?
The ratio 2 to 1 is the simplest form of the ratio 4 to 2. And the ratios are equivalent, because the relationship between each pair of numbers is the same. For example, if we have a ratio 250 to 150, we can simplify it by dividing both numbers by 10 and then by 5 to get 5 to 3: 250 : 150 25 : 15 5:3 .
What is the answer of ½ ½?
One half plus one half equals 1. Mathematically, one half is equal to 1/2. We can only add fractions that have the same denominator.

How do you compare fractions and mixed numbers?
When comparing fractions with the same denominator, the size of the numerator indicates the size of the fraction. When comparing mixed numbers, the greater the whole number, the greater the mixed fraction. If the whole numbers are the same, compare the fraction.
How do you simplify fractions?
You can simplify a fraction if the numerator (top number) and denominator (bottom number) can both be divided by the same number. Six twelfths can be simplified to one half, or 1 over 2 because both numbers are divisible by 6. 6 goes into 6 once and 6 goes into 12 twice.
How do u add fractions?
To add fractions there are Three Simple Steps:
- Step 1: Make sure the bottom numbers (the denominators) are the same.
- Step 2: Add the top numbers (the numerators), put that answer over the denominator.
- Step 3: Simplify the fraction (if possible)
What fraction is smallest?
The fraction with the smallest numerator is the smallest. The fraction with the largest numerator is the biggest. Let’s learn from an example. The fractions have the same denominators, so you just need to compare their numerators.
Is 1 2 is a natural number?
The set of natural numbers in Mathematics is the set {1, 2, 3,}. Now, -1 is a negative number, so it is not a natural number. 0 is also not a natural number. 1/2, being a fractional number, is not a natural number, either.
How do you write 2 and a half in a fraction?
You would say “two and one half.” The other format is an improper fraction where the numerator is greater than the denominator (5/2). Mathematicians would say that is five halves. You will find both types of fractions in your problems. Both of those examples represent the same value (2 1/2 = 5/2).
