QUESTIONS TO ANSWER

A fraction is part of a whole.

QUESTIONS TO ANSWER

1. WHAT ARE THE PARTS OF A FRACTION?

The parts of a fraction are the numerator and the denominator.

Numerator- the number above the line in a common fraction showing how many of the parts indicated by the denominator are taken, for example, 2 in 2/3.

Denominator- the number below the line in a common fraction; a divisor. example, 3 in 2/3.

QUESTIONS TO ANSWER

HOW ARE FRACTIONS RELATED TO DIVISION

A fraction is a division problem, in which the numerator is divided by the denominator.

Let's Practice:

Remember: A fraction is a division problem, in which the numerator(dividend) is divided by the denominator (divisor).

A fraction is a division problem, in which the numerator (dividend) is divided by the denominator (divisor). What fraction would you form from the following division problem?

Four students shared one desert. How much desert did each student get?

Day 2- Intro to Fractions

Important Terms-

FRACTION

How many parts of a whole:

NUMERATOR

The top number in a fraction.

Shows how many parts we have.

DENOMINATOR

The bottom number in a fraction.

Shows how many equal parts the item is divided
into.

COMMON DENOMINATOR

When two or more fractions have the same denominator
(the bottom number).

When do fractions need a common denominator?

We can add and subtract fractions only when they have
a common denominator.

How do you find the common denominator?

When two or more fractions have the same denominator
(the bottom number).

We can add and subtract fractions only when they have
a common denominator.

To get common denominators we can multiply both top
and bottom of a fraction by the same amount .

EQUIVALENT FRACTION

Fractions which have the same value, even though they
may look different.

Task: Write a set of equivalent fractions.

Example 1/2 and 2/4 are equivalent, because they are
both "half"
