1.	Whats is proprtional number
Answer» In today’s post we are going to work with proportions. Today, we’ll start by looking at PROBLEMS with proportionalnumbers. In order to solve problems with proportional numbers, the first step is to know the concepts of ratio and proportion. Ratio A ratio is the quotient of two numbers or quantities that are being compared to each other and it is expressed as a fraction. In other words, if we have number A and number B, their ratio is expressed in fraction a/b. Let’s check out some examples: The ratio between 6 and 2 is 3 because 6/2 = 3 The ratio between 1 and 0.2 is 5 because 1/0.2 = 5 The ratio between 100 and 10 is 10 because 100/10 = 10 If you want to PRACTICE, you can apply the ratio concept to following exercises: What is the ratio between the numbers 3 and 81? How many times bigger is the number 224 than 16? How many times smaller is the number 3 than 17? What is x’s value if the ratio between 8 and x is 1.6? What are two numbers that have a ratio of 11? Proportion But…Can we find different number pairs that have the same ratio between them? Of course we can! There are an infinite number of number pairs than meet this condition. For example, we are going to think of different number pairs that have 2.5 as their ratio: 5 and 2; 10 and 4; 100 and 40; 2,5 and 1… We can represent these by doing the following: 5/2= 10/4 = 100/40 = 2.5/1 =2.5 All of these number pairs are proportional to each other. So, we say that the numbers a, b, c and d are proportions if the ratio between a and b is the same as the ratio between c and d. This written as: a/b=c/d It’s read: a is to b as c is to d In this proportion, a and d are extremes, and b and c are means. In proportions, the PRODUCT of the means needs to be equal to the product of the extremes. So, we do this by a x d = b x c Hope it will help you

19.	What is the importance of abacus and its benefits Write in brief.Haha no one can answer this
Answer» HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤ __________________________________ __________________________________ ➡ The Importance of abacus is that the Basic mathematical operations like ADDITION, subtraction, multiplication and division are solved by simple movement of beads in this instrument. This helps the student to develop a pictorial representation of the problem in the brain and by regular practice, the brain learns to solve the problem without actual use of any aid including the abacus. The students thereby develop an exciting photographic memory. ___________________________________ ___________________________________ ➡ BENEFITS OF ABACUS ARE :- 1. It helps in boosting the calculation skills thus making them better and faster like never before. 2. Though, children have most sorted life but they still SUFFER from minor stress and PRESSURE. Therefore, abacus helps in PROVIDING them endurance for the stress and pressure they have to deal with. 3. It also helps in improving the problem solving ABILITY of the children. This training program is very effective for those who do not like studying math. ___________________________________ ___________________________________ HOPE IT HELPS U.✌✌ # BE BRAINLY.❤❤ THANKS.❤❤
