How do you write half of a number?
We can represent a number in general by x . Halving a number means dividing it by two, so the expression that shows the half of a number is x2 , since you divide a number by two.
What does less than half a number mean?
Less than one half with absolutely no context, means a number that is less than 1/2 like 1/3 or 1/4 or 2/5, or in decimal form less than 0.5 like 0.32, 0.1673 etc.
What is one half a number?
One half is the irreducible fraction resulting from dividing one by two (2) or the fraction resulting from dividing any number by its double. One half has two different decimal expansions, the familiar 0.5 and the recurring 0.49999999… It has a similar pair of expansions in any even base.
How do you write less than half?
1 ≤ 2 or 3 shows us a less than sign over half of an equal sign, so we know it means that 1 is less than or equal to 2 or 3.
How do you write 9 less than a number?
“9 less than” means you are subtracting 9 from something.
- “9 less than 12 is 3” would be written as 12−9=3.
- In the case the ‘something’ is three times an unknown number. Call the number x.
- Three times the number is 3×x=3x.
- “9 less than this” is written as 3x−9.
How do you write two and a half in numbers?
Mixed numbers have a whole number followed by the fraction (2 1/2). You would say “two and one half.” The other format is an improper fraction where the numerator is greater than the denominator (5/2).
How do you half numbers for kids?
To find one half of a number, divide it by 2. For larger numbers, split them into their tens and ones, halve these separately and then add them together. For example, to find one half of 8, we divide it by 2. Dividing by 2 means to split the total amount into two equal groups.
What fractions are less than half?
2 3 > 3 8 Two thirds is greater than one half and three eighths is less than one half. 2 4 < 5 6 Two fourths is equal to one half and five sixths is greater than one half. 4 8 < 2 3 Four eighths is equal to one half and two thirds is greater than one half. 1.
What is less than in algebra?
Greater than and less than symbols can be used to compare numbers and expressions. The less than symbol is <. Two other comparison symbols are ≥ (greater than or equal to) and ≤ (less than or equal to).
How do you write less than a number?
The less than symbol is <. Two other comparison symbols are ≥ (greater than or equal to) and ≤ (less than or equal to).
Which number is 8 less than half of a number?
This is the same as nearly everyone’s answer here. Ley no. Be x,then no. which is 8 less than half of a no. (I.e.if we decrease 8 from 1/2 of x we get the no.) be y For the part that says “a number,” this means that it has to be a variable.
What is half of a number?
1 Answer. Answer: Explanation: We can represent a number in general by #x#. Halving a number means dividing it by two, so the expression that shows the half of a number is #x/2#, since you divide a number by two.
How do you simplify y=8 less than half of a number?
Using algebra, this can be solved simply. For demonstration purposes, I’m going to change it to y = 8 less than half of a number. You can change ‘a number’ to x to simplify it. y = 8 less than half of x. The rest is even simpler. You have to rearrange the statement to figure out the rest. For example: y = half of x minus 8.
