Turning an Improper Fraction into a Mixed Number

Back 23

The numerator goes in the "box" an the denominator stays out and divide; the number that it divides into becomes the whole number, the remainder becomes the numerator, and the denominator stays the same.

Front 24

Addition of Fractions with Unlike Denominators

Back 24

1. Find the LCD of each denominator

2. If the denominator is changed, the numerator must also be changed by the same number by multiplying the numerator and denominator by the same number

3. Add the numerators together, and keep the common denominator

4. Reduce the fraction if necessary

Front 25

Addition of Mixed Numbers

Back 25

1. Leave the whole number alone and focus solely on the fraction

2. Find the least common denominator of the fractions

3. If the denominator is changed, the numerator must also be changed by the same number by multiplying the numerator and denominator by the same number

4. Bring back the whole numbers to their designated fraction

5. Add together the whole numbers

6. Add together the numerators and keep the common denominator

7. Reduce the fraction if necessary

Front 26

Subtracting Fractions with Unlike Denominators

Back 26

1. Find the LCD of the fractions

2. If the denominator is changed, the numerator must also be changed by the same number by multiplying the numerator and denominator by the same number

3. Subtract the numerators and keep the denominators the same

4. Reduce the fraction if necessary

Front 27

Multiplication of Fractions

Back 27

1. Multiply the numerators together

2. Multiply the denominators together

3. Reduce the fraction if necessary

Front 28

Division of Fractions

Back 28
