What is a fraction?

Back

A fraction represents a part of a whole. It is written as 'a/b', where 'a' is the numerator (the number of parts we have) and 'b' is the denominator (the total number of equal parts).

What does equivalent fractions mean?

Back

Equivalent fractions are different fractions that represent the same value or proportion of a whole. For example, 1/2 and 2/4 are equivalent fractions.

How do you find the total number of boxes needed if you have a total number of items and a fixed number of items per box?

Back

To find the total number of boxes needed, divide the total number of items by the number of items per box. For example, if you have 54 muffins and each box holds 6 muffins, you would calculate 54 ÷ 6 = 9 boxes.

Front

What is expanded form in mathematics?

Back

Expanded form is a way of writing numbers to show the value of each digit. For example, the expanded form of 92,060 is (9 × 10,000) + (2 × 1,000) + (6 × 10).

Front

How do you compare fractions?

Back

To compare fractions, you can find a common denominator or convert them to decimals. You can also use visual models to see which fraction is larger or smaller.

Front

What is the perimeter of a shape?

The perimeter is the total distance around the outside of a shape. To find the perimeter of a polygon, add the lengths of all its sides.

Front

What is an octagon?

Back

An octagon is a polygon with eight sides and eight angles.

Front

How do you calculate the perimeter of an octagon?

Back

Front

What does it mean when a fraction is greater than another fraction?

Back

A fraction is greater than another fraction if it represents a larger part of a whole. For example, 2/4 is greater than 1/4.
