Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.

It depends on what problem 4 is.

Subtracting two positive fractional numbers, or adding one positive and one negative integer.

They are similar because when you compare decimals you say the larger one has more value so the decimal is larger like in comparing whole numbers the number that has more value is larger. So they are very similar.

Subtracting a fraction is the same as adding its negative.

In that you carry out exactly the same steps - AND you must determine the correct position of the decimal point.

They are different because a ratiocompares two different numbers or measurements from different units but the rate does not. They are similar because they both compare numbers. EX) ratio: 4/3 rate: 1.333 etc.

They are similar in the sense that they cannot be broken down any further. They are however different in that they have different atomic numbers.

When their denominators are the same or different numbers.

You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.

they can be change into each other

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.

Adding whole numbers is the addition of decimals where the decimal part is zero; in both cases the digits are place value aligned meaning that the decimal points, which lies between the units (or ones) and tenths columns, are aligned - in the whole number the decimal point is "hiding" at the end.

Similar fractions. or decimals ending in repeating 9s - for example, 0.5 = 0.4999... or fractions and percentages eg 1/5 = 20% The answer cannot be numbers equal in absolute value but with opposite signs because although they have the same absolute value they do not have the same value - as required by the question.

Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify..

If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).

similar-a similar radicand is to add or subtract similar radicals we simply add and subtract there coefficients and Anex to the sum of their common radical part.
