You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
Very.
Is the rounding is skidding
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.

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