# Grade 5 - Fractions Chapter 7 - Basic

## 24 terms

### Fraction

names a part of a whole set

### Numerator

tells how many parts are shaded/not shaded in a set. ex: in the fraction ¾, the 3 is the numerator

### Denominator

tells how many total parts are in the whole set ex: in the fraction ¼, the 4 is the denominator

division

### Mixed Number

combination of a whole number and a fraction together ex: 4½

### Improper Fraction

a fraction where the numerator is larger then the denominator ex: 21/4

### How to change an improper fraction to a mixed number

1. Divide the numerator by the denominator 2. Write the remainder at a fraction

### How to change a mixed number into an improper fraction

1. Multiply the denominator by the whole number 2. Add the numerator 3. Use the same denominator in the new fraction

### Benchmark Fractions

fractions that help to estimate fractional amounts (1/4, 1/3, 1/2, 2/3 and 3/4)

### Equivalent Fractions

2 or more fractions that name the same part of a whole

### How to find equivalent fractions

you can multiply or divide the numerator & denominator by the same number to find an equivalent fraction

### Factor

a number multiplied to find a product

### Common Factor

the multiplication facts that 2 or more numbers are part of (have in common)

### Greatest Common Factor (GCF)

the greatest (largest) factor that 2 or more numbers have in common

### Simplest Form

when the numerator and denominator have no common factors other than 1 ( a fraction cannot be made any smaller)

### How to find simplest form

divide the numerator & denominator by their greatest common factor (GCF)

### Common Denominator

when 2 or more fractions have the same denominator

### How to compare fractions with different denominators

find the common denominator of each fraction

### Least Common Denominator

the first (smallest) number in each multiplication table they denominators have in common

### 10ths as the denominator written as a decimal

2/10 = 0.2 6/10 = 0.6

### 100ths as the denominator written as a decimal

34/100 = 0.34 59/100 = .59

### 1,000ths as the denominator written as a decimal

543/1,000 = 0.543 98/1,000 = 0.098

### 21/4= 5¼ 21÷4 = 5 (whole number); remainder is 1 (numerator); denominator was 4 so it stays the same...this is an example of...

an improper fraction changing to a mixed number

### 5¼ = 21/4 So, 5 (whole number) x 4 (denominator) = 20; 20 + 1 (numerator) = 21 (your new numerator); the denominator was 4 so it stays the same 21/4...this is an example of...

a mixed number changing to an improper fraction
