Guppies (45), zebra fish (25), and tiger barb (26) are all < 60 in number. Which type of fish are less than 60 in number? Fun Factsīritish mathematician Thomas Harriot first used the sign for less than (<) in 1631, in his book Artis Analyticae Praxis ad Aequationes Algebraicas Resolvendas.Įxample 1: Select the numbers that are smaller than 20 from the given set of numbers.Ġ, 14, 21, 20, 18, 22, 36, 45, 12, 3, 15, 99, 27Ġ, 14, 18, 12, 3, 15 – are all numbers < 20.Įxample 2: In an aquarium, there are various types of fish. Without comparison, it is difficult to show the equality or inequality between things that we see around us. To sum up, comparison plays a significant role in our lives. A filled circle shows that the limit value is also the solution to given inequality. Note: If the inequality was “less than or equal to” we would have filled the circle. Starting from the empty circle(limit value), extend an arrow to the left end signifying all the values the variable x can have. Step 2: The inequality x < 3 shows that the variable x is allowed to have any value smaller than 3, which means all the values on the left of this circle. Step 1: Locate “3” on the number line and mark it with the empty circle. Let’s look at the steps to represent inequality of the form x < 3 on the number line. Below are six versions of our grade 4 fractions worksheet on comparing (less than, greater than, equal to) proper fractions with different denominators. The empty circle shows that a limit value is not the solution to the given inequality. To show the lesser than sign on the number line, we use an empty circle to mark the limit value and point an arrow towards the given condition of inequality. Therefore, Rita and Suma together have fewer chocolates than John. The total number of bars that Rita and Suma have = 2 + 3 = 5 bars Does John have more chocolates than Rita and Suma combined? Rita has 2 bars of chocolates and Suma has 3 bars of chocolates. So, the bag of tomatoes weighs less and Ray hands it to his son, while he carries the bag of potatoes.Įxample 3, John has 6 bars of chocolates. There are two bags, the one with the potatoes weighs 8 lb, and the other that has tomatoes weighs 4 lb. Well, for that, it is important to find out which bag is lighter. He hands over the lighter bag to his son. On comparing the two, it is clear that Bowl A has fewer marbles than Bowl B.Įxample 2, Ray buys 8 lb of potatoes and 4 lb of tomatoes and puts them in two separate bags. Let’s look at some examples of less than.Įxample 1, there are 4 marbles in Bowl A, and 7 marbles in Bowl B. The less than symbol is “ <” and with this metric, we can compare numbers, weights, heights, and values. It states that one value is lesser than or lower than or fewer than or smaller than the other. Since I can't explain it or draw it very well here's a link that could help you.It is one of the terms used to show a relationship between two values. This is a real shortcut in math when you're in a big hurry. Since 2/5 is a smaller amount to get to a whole than 1/3, 3/5 is greater. For 1/3 however you'll need 2/3 more to get to a whole. 1-3/5 is greater than 1/3 because on the fraction diagram for 3/5, you only have 2/5 more to get to a whole. Your explanation should be close to this.Įx. If we look on the fraction diagram 3/5 should be your answer. Let's say we have the fractions 1/3 and 3/5. For this way you'll need a fraction chart of all of the fractions from parts to 1/2 to 1/12. This way is for people who like to be thorough in their math. We are now asking students to look at two different written fractions and use comparing language like greater than, less than, or equal to. We could easily tell which one is greater by turning them into percents.Īs you can see, the greatest fraction out of 4/5 and 2/3 is 4/5. We could easily tell which fraction is greater by turning them into percents. You can easily see the greatest fraction is 64/72 or 8/9 because 64 is greater than 63.įrom fourth grade, all of you are supposed to know your percents and what fraction and decimal they equal. Now your new fractions that can be reduced to your regular fractions (7/8 and 8/9) are now 7/8=63/72 and 8/9=64/72. So now we have to change the numerators to the numbers we multiplied to get the denominator 72. Now we have to find the LCM of the two numbers. If we look at the two denominators, they're both 8 and 9. For example let's say our two fractions were 7/8 and 8/9. LCD is the same thing except the LCM is the denominator. Least Common Multiple- The smallest number two or more numbers share. So most people know what least common multiple, right? Here are some ways to tell which fraction is greater. There is the LCD (least common denominator), percentages, visualization, and criss-cross multiplication. There are may ways on telling which fraction or ratio is largest.
