noun (fraction, fractions)

«fraction» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

1. A fraction is a part of a whole, like one half or three quarters. It is written with one number over another, like 3/4. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/F/fraction/#m1)
2. The bottom number (denominator) tells how many equal parts the whole has; the top number (numerator) tells how many parts we take. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/F/fraction/#m2)
3. A fraction of something can also mean a very small part of it. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/F/fraction/#m3)

### In the lessons

maths: a part of a whole or of a group; problems ask for a fraction of an amount or what fraction is left; equal fractions, comparing and adding fractions; everyday life: half a pizza, a quarter of an hour; science: a fraction of a second

### Examples

### Note

«A fraction of» an amount means multiply (or divide by the bottom number and multiply by the top). Trap: «what fraction is left» needs the part left over the whole, not the part taken. The parts must be equal for a fraction.
