Understanding of Fractions as Numbers

How is fraction as a part of a whole?We know, a fraction means a part. So, fraction is the part of a whole object.Thus, a fraction is the part of a collection or collections of objects.A fraction is a part of a whole number say 1, 2, 3, 4, ……. 150 ……. etc.Thus, a number which is not a whole number is known as a fractional number.For example; 1/2, 1/3, 2/3, 3/4, 5/6, …………… are fractional numbers.

Develop understanding of fractions as numbers.CCSS.Math.Content.3.NF.A.1Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

A fraction is a numerical quantity that is not a whole number ex: 3/4 or 2/3

You often need to know when one fraction is greater or less than another fraction. Since a fraction is a part of a whole, to find the greater fraction you need to find the fraction that contains more of the whole. If the two fractions simplify to fractions with a common denominator, you can then compare numerators. If the denominators are different, you can find a common denominator first and then compare the numerators. Determining Equivalent Fractions Two fractions are equivalent fractions when they represent the same part of a whole. Since equivalent fractions do not always have the same numerator and denominator, one way to determine if two fractions are equivalent is to find a common denominator and rewrite each fraction with that denominator. Once the two fractions have the same denominator, you can check to see if the numerators are equal. If they are equal, then the two fractions are equal as well. One way to find a common denominator is to check to see if one denominator is a factor of the other denominator. If so, the greater denominator can be used as the common denominator.

Fractions are parts of a whole

Understanding FractionsIf you don't understand fractions, you won't be even 1/3 educated. Glasses will seem half empty rather than half full. You'll be lucky to not be duped into some type of shady real-estate scheme or putting far too many eggs in your cake batter. You'll see that fractions allow us to view the world in entirely new ways. You'll see that everything doesn't have to be a whole. You'll be able to slice and dice and then put it all back together.

Cool Fraction Games!
