Understanding Decimal Fractions: Converting Decimals to Fractions and Fractions to Decimals
This clip explains that, "
.changing a decimal to a fraction or a mixed number isn't much trouble," then proceeds to illustrate that statement with examples. The clip adds that the fraction may be (but doesn't have to be) reduced to the lowest term...
Adding Rational Expressions with Different Denominators
Rational expressions with different denominators are added and the procedure explained.
Adding and Subtracting Rational Expressions
The rules for adding and subtracting rational expressions are similar to those for adding and subtracting rational numbers, beginning with the rule that in order to be added, rational numbers must have the same denominator. Addition examples are dem...
Denominator of a Simplified Expression Never Has Radicals, The
A guideline is presented: a simplified radical expression never has radicals in the denominator. An expression with a radical in the denominator, but not in the numerator, is simplified using the identity property of multiplication and the process o...
Division with a Binomial in the Numerator
Examples of simplifying radical expressions with division when numerators contains a binomial.
Examples of Division Problems with Radicals
Two division problems with radicals are demonstrated.
Dividing a Radical by a Whole Number
A radical can only be divided by another radical. In the examples demonstrated, the only radical is in the numerator. The radical simplified and the fraction reduced.
