F situ are the pits. I am not too bad. But since addition is the most popular arithmetic operation, that & # 39; s where the darn problem is. I mean those I am multiplying and dividing them. pesky denominators always get in the way. looking at the price of gas, which is hovering about $ 3.00 per gallon and you see something like "Unleaded Regular - $ 2.79 9/10"; at the unit prices in supermarkets and you might see something like 33 c cents per pound, or 16 1/3 cents per ounce. Let 's face, you' re not escaping these little monsters so you better just get used to them.
You just need some some tools that will help you or your child deal a death blow to the seemingly unending array of problems that fragments can cause.
An important point to make here is that fractions are an integral part of any child & # 39; s mathematical education, and, if not taught properly, can strictly hinder progress in this subject: all of mathematics any directly or indirectly due to numbers, and yes, fractions make up a large part of the real number. As pointed out above, you can not frustrated with fractions because you can not add or subtract them like one with with ordinary numbers. With fractions, you need a common denominator before the addition or subtraction operation is negotiated ..
For example, to add 3/10 and 2/15 all you need do is ask, "What is common to 10 and That's what is the largest number that dives both 10 and 15? The largest number to do this feat is 5, and this is known as the greatest common factor of 10 and 15. Thus multiply 10 and 15 together to get 150 , then divide this result by 5 to get 30. This last number is the least common denominator of both 10 and 15. Now to finish off our problem of adding 3/10 and 2/15 we find out how many times each of the denominators go this into the number 30. In this case we have 30/10 is 3 and 30/15 is 2. We multiply each of these quotients 3 and 2 by the relevant numerators 3 and 2 to get 3 x 3 is 9 and 2 x 2 is 4. We add these last two results, 9 and 4, to get 13. We put this number over the common denominator 30 to get our final answer of 13/30. That & # 39; s it folks. Noth ing too hard to learn. And this method works all the time.
I have fate! "Into one of" I love fractions I love fractions ! "Just watch your kids & # 39; grades soar in mathematics once they master fractions.
