### Identifying Numerator, Denominator, and Unit

Every fractional measurement needs to contain three pieces of information:- The
**denominator** tells me the name of the parts being used.

- The
**numerator** tells me how many of those pieces are filled.

- The
**unit** is whatever was broken up to make those pieces.

So, for example, if I say "three fourths of a cup," then I have three pieces, where each is a fourth part made from a cup. So, "three" is the numerator, "fourths" is the denominator, and "cup" is the unit.- The picture below shows some fractional number of turps.

a) What is the...

Unit? | Numerator? | Denominator? |

b) How would I write this measurement in words?

c) How would I write this measurement in math?

d) How would I write, in math, that this amount is the same as three gorfs?

- The picture below shows a number line split into pieces.

a) What is the...

Unit? | Numerator? | Denominator? |

b) How would I write this measurement in words?

c) How would I write this measurement in math?

d) How would I write, in math, that this amount is seventy two?

- A box of paper contains ten reams. I used up seven reams. I want to write that as a fraction of a box.a) What is the...

Unit? | Numerator? | Denominator? |

b) How would I write this measurement in words?

c) How would I write this measurement in math?

d) How would I write, in math, that this amount is three thousand, five hundred pages?

### Fractions on a Number Line

- Below, draw me a number line to find out:
**What is three fifths of twenty?**

- Below, draw me a number line to find out:
**5/3 × 60 = ?**

- Below, draw me a number line to find out:
**What is seven halves of sixteen?**
