What are identical fractions?
Equivalent fractions are two or more fractions that space all equal. A portion is a component of a whole: the denominator (bottom number) to represent how many equal parts the entirety is separation into; the numerator (top number) represents the quantity of those parts.
Confused around fractions? You’re not alone
If the ide of equivalent fractions already sounds a little bit confusing and also you’re not yet clean on what the difference is between whole numbers, denominators of a portion and different numerators you might want come loop ago to our fountain for youngsters article
This breaks down the first fraction procedures that an essential Stage 1 and crucial Stage 2 children must take it at school, together with clear instances of how to find the worth of a portion using concrete resources, pictorial representations and also number lines; the difference in between unit fractions and also non unit fractions; all the way up come proper and improper fractions.

How to work-related out equivalent fractions
To calculate equivalent fractions, both the numerator and denominator have to be multiply by the very same number. Because that example, to find fractions tantamount to 3/5:
3/5 x 2/2 = 6/10 (x 2/2 method multiplying both the numerator and also denominator by 2. Any fraction where the numerator and denominator are the very same is same to 1. Multiply anything by 1 doesn’t change the initial number, therefore we recognize the fraction will it is in equivalent)
3/5 x 3/3 = 9/15
3/5 x 4/4 = 12/20
So, 3/5 = 6/10 = 9/15 = 12/20.
Another method to uncover equivalent fractions is to divide both the numerator and the denominator that the fraction by the same number – this is called simplifying fractions, due to the fact that both the numerator and also denominator number will gain smaller.
For example, to leveling 9/12, uncover a number that both the numerator and denominator deserve to be divided by (also recognized as a ‘common factor’), such together 3.
9/12 ÷ 3/3 = 3/4, for this reason 9/12 and also 3/4 are tantamount fractions, with 3/4 gift the fraction in its easiest form.
When will certainly my boy learn around equivalent fractions in major school?Equivalent fractions KS2
The principle of indistinguishable fractions isn’t presented until Year 3, where children recognise and show, utilizing diagrams, indistinguishable fractions with little denominators.
In Year 4, they will certainly recognise and also show, using diagrams, family members of typical equivalent fractions. The nationwide Curriculum’s non-statutory guidance also advises that pupils usage factors and also multiples come recognise identical fractions and also simplify where proper (for example, 6/9 = 2/3 or ¼ = 2/8).
In Year 5, pupils space taught come identify, name and also write equivalent fractions of a offered fraction, stood for visually, including tenths and also hundredths. In Year 6, they will add and subtract fractions with different denominators and also mixed numbers, utilizing the principle of tantamount fractions. Non-statutory guidance for Year 6 says that common factors can be pertained to finding identical fractions and that children practise calculations with simple fractions… including listing tantamount fractions to determine fractions with typical denominators.
How do equivalent fractions relate come other areas of maths?
Children will have to understand tantamount fractions to have the ability to convert in between fractions, decimals and also percentages. Knowledge of times tables, the lowest common multiple and highest common factor are likewise important for indistinguishable fractions
