Fractions

To convert mixed numbers to improper fractions, multiply the whole number by the denominator, then add the numerator, and write the answer over the original denominator.

To convert improper fractions to mixed numbers, divide the numerator by the denominator. The answer becomes the whole number, and the remainder becomes the numerator of the fraction part of your answer. The denominator remains the same.

Convert everything to improper fractions and order by the numerator.

Divide the numerator and denominator by the same number. Keep doing this until it is no longer possible.

To find an equivalent fraction, multiply the numerator and denominator by the same number.

To put fractions in order, convert all fractions to equivalent fractions with the same denominator, then put them in order.

If fractions have the same denominator, to add these fractions, add the numerators but not the denominators.

If fractions, have the same denominator, to subtract these fractions, subtract the numerators but not the denominator.

To add fractions with different denominators, you must first convert them to fractions that have the same denominator, then add the numerators.

To subtract fractions with different denominators, you must first convert them to fractions that have the same denominator, then subtract the numerators.

To find a fraction of an amount, divide the amount by the denominator, then multiply it by the denominator.

To multiply fractions, multiply the numerators, and multiply the denominators.

To divide fractions, keep the first fraction as it is, change the division to a multiplication, then flip the second fraction upside down.
