Now girlfriend know around regular fractions through numerators on top and denominators on the bottom. Fractions can be hopeful or negative. Until now, we have actually just looked at fractions the are less than one. The didn"t issue whether it to be one half (1/2) or ripe hundred ninety-nine one-thousandths (999/1000), the values were still much less than one.When you have a fraction that is greater than one, it have the right to come in 2 formats. Mixed numbers have actually a entirety number followed by the fraction (2 1/2). You would say "two and one half." The other style is one improper fraction whereby the molecule is greater than the denominator (5/2). Mathematicians would certainly say the is 5 halves. Friend will uncover both species of fountain in your problems. Both the those instances represent the very same value (2 1/2 = 5/2). Here"s why...• 2 1/2 is the very same amount as two totality objects and half of a third.• You can break those two totality objects right into halves as well. If each object had two halves, then 2 objects would provide you a complete of four pieces (2x2=4).• That way you have four halves native the totality objects and one-half the a third.• friend would have a complete of 5 halves. You have the right to write 5 halves together 5/2.Different ways of Writing combined NumbersAs we just told you, a mixed number is a whole number through the fraction written come its appropriate side.• 2 1/2, 5 8/13, 6 4/7You will generally see the portion written in its easiest form.• 6 4/7 correct• 6 8/14 not correct (needs to it is in reduced)You might have problems that ask you come simplify combined numbers. Don"t worry. You commonly don"t worry about the totality number. As soon as you simplify, simply worry about the fraction.

You are watching: 2 1/2 improper fraction

Example:Simplify 8 4/8• just worry about simplifying the fraction 4/8.• We"ll divide by the common factor 4 and get 1/2.• The simplified mixed number is 8 1/2.Another format for a portion that is higher than one is the improper fraction. They are called "improper", because fractions are always supposed to be written through a numerator (number top top top) that is less than the denominator (number ~ above the bottom). 2/3 is a suitable fraction. 3/2 is an improper fraction because 3 > 2. They are valuable in plenty of problems when you include fractions and also subtract fractions. Friend will also use improper fractions as soon as you occupational with reciprocals.Is 1/3 an wrong fraction? No. 1 Is the mutual of 8/11 an not correct fraction? Yes.

 The reciprocal is 11/8. 11/8 is an wrong fraction.So, we deserve to make an improper fraction by finding the reciprocal. Friend may additionally need to do an improper portion from a blended number. We just did that above, yet let"s execute it one an ext time...Example:Write 2 1/2 together an not correct fraction.• The equivalent of two is 2/1 or 4/2. If you are unsure, inspect using division.• Rewrite the mixed number as an enhancement problem. 2 1/2 = 2 + 1/2• substitute the new value that two. 2 + 1/2 = 4/2 + 1/2• using a little portion addition... 4/2 + 1/2 = 5/2• 5/2 is an improper fraction that is identical to 2 1/2.
