What is a non-unit fraction in year 3? ›

A unit fraction is any fraction where the numerator is 1, eg ¼. A non-unit fraction is a fraction where the numerator is not 1, eg ⅘.

Your child will learn to compare unit fractions (fractions with a numerator of 1) and fractions with the same denominator. They will be able to say which fraction is bigger or smaller and why. They will be able to put a list of these kinds of fractions in order (for example, biggest to smallest).

Fractions represent the parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken. The number below the line is called the denominator.

A unit fraction is a positive fraction with one as its numerator, 1/n. It is the multiplicative inverse (reciprocal) of the denominator of the fraction, which must be a positive natural number. Examples are 1/1, 1/2, 1/3, 1/4, 1/5, etc.

Non-unit fractions could be proper fractions (less than 1 whole, where the denominator (bottom number) is larger than the numerator) or improper fractions.

A formal introduction to fractions begins in Grade 3, where the Number and Operations—Fractions domain first appears in the mathematics standards.

To divide a proper fraction by a whole number when the numerator isn't divisible by the whole number, we need to use the inverse operation of multiplication. Simply multiply the denominator of the fraction by the whole number and the numerator of the fraction by one, simplifying the answer if needed.

– If the numerator is 0, then the entire fraction becomes zero, no matter what the denominator is! For example, ⁰⁄₁₀₀ is 0; ⁰⁄₂ is 0, and so on. The word “numerator” is derived from the Latin word numerātor, which means counter. If the numerator is the same as the denominator, the value of the fraction becomes 1.

Answer: Thus, the required fraction will be 100 / 1.

Any number can be represented in the form of a fraction.

Equivalent fractions are often found by multiplying or dividing by the same number to both numerator and denominator. For example, 4/8 can be divided by 2 to find 2/4. Or, 4/8 can be multiplied by 2 to find 8/16. Both of these fractions are equal to 1/2.

Which fraction is bigger? ›

As long as the denominators are the same, the fraction with the greater numerator is the greater fraction, as it contains more parts of the whole. The fraction with the lesser numerator is the lesser fraction, as it contains fewer parts of the whole.

Any fraction with a numerator other than 1 is a non-unit fraction. For example, 3/4, 3/8, 2/3, etc are all non-unit fractions.
