Study Notes
Dividing Fractions and Mixed Numbers
- A fraction is a number written in the form a/b, where a is the numerator and b is the denominator.
- Multiplying two fractions involves multiplying the numerators and denominators to create a new fraction.
- Dividing fractions is not as straightforward and can be confusing.
Dividing Fractions
- Dividing by a number is the same as multiplying by its reciprocal.
- Dividing by a fraction is the same as multiplying by its reciprocal.
- For example, dividing by 2 is the same as multiplying by 1/2.
- The strategy for dividing fractions is to multiply by the reciprocal of the divisor.
Examples of Dividing Fractions
- To divide a fraction, multiply by the reciprocal of the divisor.
- For example, ? = × =
- A whole number can be rewritten as a fraction, making it easier to perform the operation.
- For example, 2 = 2/1, making it easier to divide by a fraction.
Dividing Mixed Numbers
- A mixed number is a whole number plus a fraction, and can be converted into an improper fraction.
- To convert a mixed number to an improper fraction:
- Take the whole number and turn it into a fraction with denominator 1.
- Multiply the numerator and denominator of the whole number by the denominator of the fraction portion.
- Add the two fractions together.
Examples of Dividing Mixed Numbers
- To divide mixed numbers, convert them into improper fractions and then divide.
- For example, ? = ? =
- Convert the mixed numbers into fractions, then divide the fractions.
Division of Mixed Numbers and Fractions
- When both fractions and mixed numbers are involved, division can appear complicated.
- The process is the same as above: turn all mixed numbers into improper fractions and then divide the fractions.
- Divide mixed numbers and fractions by converting mixed numbers to improper fractions and then dividing using the reciprocal method.
Examples of Division of Mixed Numbers and Fractions
- To divide mixed numbers and fractions, convert the mixed numbers to improper fractions and then divide.
- For example, ? = ? =
