What is a fraction?

Back

A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, 1/2 means one part out of two equal parts.

How do you estimate a fraction of a whole?

Back

To estimate a fraction of a whole, you can visually assess the parts and compare them to the total. For example, if a garden is divided into 8 equal parts and 3 are planted with tomatoes, you can estimate that about 3/8 of the garden is planted.

Front

What does it mean to simplify a fraction?

Back

Simplifying a fraction means reducing it to its simplest form, where the numerator and denominator have no common factors other than 1. For example, 4/8 can be simplified to 1/2.

How do you find the fraction of items left after some are removed?

Back

To find the fraction of items left, subtract the number of items removed from the total number of items, then divide by the total. For example, if there are 10 llamas and 3 wander away, the fraction left is (10-3)/10 = 7/10.

Front

What is the meaning of 'about' in estimating fractions?

Back

'About' indicates an approximation rather than an exact value. For example, saying 'about 1/2' means the actual fraction is close to 1/2 but not necessarily exactly that.

Front

How do you divide a whole into equal parts?

Back

To divide a whole into equal parts, you determine how many parts you want and then split the whole accordingly. For example, if you have a pizza with 12 slices and want to share it among 4 people, each person gets 12/4 = 3 slices.

Front

What is the relationship between fractions and division?

Back

Fractions can be understood as division. The fraction a/b means 'a divided by b'. For example, 3/4 means 3 divided by 4.

Front

How do you compare two fractions?

Back

To compare two fractions, you can find a common denominator or convert them to decimals. For example, to compare 1/2 and 3/4, convert them to a common denominator of 4: 1/2 = 2/4, so 3/4 is greater.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction. For example, 1 1/2 means one whole and one half.

Front

How do you convert an improper fraction to a mixed number?

Back

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient is the whole number, and the remainder becomes the numerator of the fraction. For example, 9/4 = 2 1/4.
