Whichever number is larger, the alligator mouth is opened towards that number. If you were given 5 and 8 and were told to show which number is greater than or less than, the alligator would open his mouth towards the 8. This shows that 5 is less than 8. The same would work if you were given 10 and 4. The alligator mouth would open towards the 10, showing that the 10 is greater than 4. Jay Willis joined Mometrix as Vice President of Sales in , and has developed several key strategic relationships that have enhanced the distribution of Mometrix products.
The "Greater than or equal to" symbol is used in linear inequalities when we don't know whether the value of a variable is greater than or equal to a particular value. The sleeping line below the greater sign means "equal to". Here is an example for you to understand this concept better. For a school to participate in an olympiad exam, the number of students from each class should be a minimum of This means that if there are less than 10 students participating from any one of the classes, none of the students of that class can take the olympiad exam.
If x represents the number of students participating in a class, then x should be greater than or equal to The table below shows where and how greater than or equal to symbol is used along with examples and meanings.
Check out the important topics mentioned below to learn more about the greater than or equal to and its related topics. If x is the number of glasses of juice that he sells in a day, write an inequality representing this situation.
Example 2: James needs to score a minimum of 40 marks out of to clear the math exam. Express this statement using the greater than or equal to symbol. Solution: Let's represent the math marks of James by x.
It is given that passing marks are 40 or more. Solution: We know that N is the set of natural numbers. Since the set of natural numbers is infinite, the numbers that belong to the given set are, 3,4,5,6, Greater than or equal to as the name suggests, means something is either greater than or equal to some quantity. The open side of the symbol should be in front of a bigger value.
It could be 4 cups or it could be less than 4 cups: So until we measure it, all we can say is "less than or equal to " 4 cups. To show this, we add an extra line at the bottom of the "less than" or "greater than" symbol like this:.
Always make sure the small end points to the small value. Answer: Let us call the longer length of rope " L ", and the shorter length " S ". Do you see how neat mathematics is?
NOW, I have one more trick. If Sam tried really hard he might be able to cut the rope EXACTLY in half, so each half is 5m, but we know he didn't because we said there was a "shorter" and "longer" length, so we also know:.
OK, this example may be complicated if you don't know Algebra , but I thought you might like to see it anyway:.
