Division Division is a process that reduces the value. Division is the inverse of multiplication. It has the same relationship to multiplication that subtraction has to addition.
For example, if you begin with 3 and multiply it by 5 (3 x 5), you need only divide the result (15) by 5 to once again have 3. In other words, it reversed the original process. In a division problem such as 15 ÷ 5 = 3:
This operation is usually indicated by a "÷" sign or by the slanted or horizontal line in a ratio or fraction, as indicated by "/" in the fraction 3/4. Order of operations The operations of multiplication and division are performed first in most mathematical and statistical equations, unless parentheses indicate a sub-operation to be performed first or exponents or square roots need to be calculated (after any sub-operations in parentheses). Refer to www.math.com for tutorials and interactive exercises on division. Similar to multiplying fractions there are no requirements regarding equal denominators. However, instead of multiplying the numerators and multiplying the denominators, in division the numerator of each fraction is multiplied by the denominator in the other fraction (in practice it can easier to flip one of the fractions and proceed with normal multiplication rules). Divide 3/7 by 2/9: |
