Factor :D
For example: 1/2+1/4+1/8 are dissimilar fractions but also a rational expression that can be simplified to 7/8
multiplying rational expressions means multiplying two alg. rxpressions that look like fractions, Just like normal, multiply numerators and multiply denominators then reduce. Division, just like regular fractions means to invert the divisor and the multiply (as above)
Fractions are not integers. They may or may not be rational numbers.
All fractions are rational numbers.
a rational function.

similarities and differences between ordinary fractions and rational expressions.
How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions?If you know how to do arithmetic with rational numbers you will understand the arithmetic with rational functions! Doing operations (adding, subtracting, multiplying, and dividing) is very similar. When you areadding or subtracting they both require a common denominator. When multiplying or dividing it works the same for instance reducing by factoring. Operations on rational expressions is similar to doing operations on fractions. You have to come up with a common denominator in order to add or subtract. To multiply the numerators and denominators separated. In division you flip the second fraction and multiply. The difference is that rational expressions can have variable letters and powers in them.
For example: 1/2+1/4+1/8 are dissimilar fractions but also a rational expression that can be simplified to 7/8
Rational expressions are fractions and are therefore undefined if the denominator is zero; the domain of a rational function is all real numbers except those that make the denominator of the related rational expression equal to 0. If a denominator contains variables, set it equal to zero and solve.

Yes. Rational functions must contain rational expressions in order to be rational.
Fractions are not integers. They may or may not be rational numbers.
Yes, mixed fractions are rational
All fractions are rational numbers.
