NF.1 & NF.2 Pretest

Front

What is a fraction?

Back

A fraction represents a part of a whole. It consists of a numerator (the top number) and a denominator (the bottom number). For example, in the fraction 1/2, 1 is the part and 2 is the whole.

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 1/3 and 1/6, you can see that 1/3 is greater because it represents a larger part of the whole.

Front

What does it mean for two fractions to be equivalent?

Back

Two fractions are equivalent if they represent the same part of a whole, even if they have different numerators and denominators. For example, 1/2 and 2/4 are equivalent fractions.

Front

How do you find the fraction of a set?

Back

To find the fraction of a set, divide the number of parts you are interested in by the total number of parts. For example, if there are 10 apples and 3 are red, the fraction of red apples is 3/10.

Front

What is the meaning of the numerator in a fraction?

Back

The numerator is the top number in a fraction that indicates how many parts of the whole are being considered. For example, in the fraction 3/4, 3 is the numerator.

Front

What is the meaning of the denominator in a fraction?

Back

The denominator is the bottom number in a fraction that indicates the total number of equal parts the whole is divided into. For example, in the fraction 3/4, 4 is the denominator.

Front

How do you add fractions with the same denominator?

Back

To add fractions with the same denominator, simply add the numerators and keep the denominator the same. For example, 1/4 + 2/4 = (1+2)/4 = 3/4.

Front

How do you subtract fractions with the same denominator?

Back

To subtract fractions with the same denominator, subtract the numerators and keep the denominator the same. For example, 3/5 - 1/5 = (3-1)/5 = 2/5.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction. For example, 2 1/2 is a mixed number, which means 2 whole parts and 1/2 of another part.

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, 7/4 = 1 3/4.
