Suppose p/q and r/s are rational numbers where p, q, r and s are integers and q, s are non-zero.Then p/q + r/s = ps/qs + qr/qs = (ps + qr)/qs.Since p, q, r, s are integers, then ps and qr are integers, and therefore (ps + qr) is an integer.q and s are non-zero integers and so qs is a non-zero integer.Consequently, (ps + qr)/qs is a ratio of two integers in which the denominator is non-zero. That is, the sum is rational.Also p/q * r/s = pr/qs.Since p, q, r, s are integers, then pr and qs are integers.q and s are non-zero integers so qs is a non-zero integer.Consequently, pr/qs is a ratio of two integers in which the denominator is non-zero. That is, the sum is rational.
Suppose x and y are two rational numbers. Therefore x = p/q and y = r/s where p, q, r and s are integers and q and s are not zero.Then x - y = p/q - r/s = ps/qs - qr/qs = (ps - qr)/qsBy the closure of the set of integers under multiplication, ps, qr and qs are all integers,by the closure of the set of integers under subtraction, (ps - qr) is an integer,and by the multiplicative properties of 0, qs is non zero.Therefore (ps - qr)/qs satisfies the requirements of a rational number.
The answer will depend on whether the number is 0.717171... or 0.711111...
Quad Strike or Quick Strike. (QS)
Queer sort
erhh.. quick silver
There are questions, or there is qs
QS can refer to several things depending on the context. In business, QS often stands for "Quantity Surveyor," a professional who estimates and manages construction costs. In healthcare, QS can refer to "Quality of Service," which measures the level of service provided to patients.
"qs" likely stands for "questions." In the context of text messaging or online communication, it is commonly used as an abbreviation to refer to questions.
None in English, if you mean paired Qs.
In the construction industry, what is the role of a QS??
preparing medication for a specific patient
The term Keeping up with your Ps and Qs is generally quoted as Minding your Ps and Qs. This is an old term, which means to Mind your Pints and Quarts, which means to mind your own business, basically, or to take care of a task.
Hi There, QS means to add enough of the major ingredinet until you have a total of 100% of the formula. It also stands for quantity sufficient. MDW
X Qs me. 'Excuse me'. Possibly also an exaggerated form, 'Excuuuuse me!'.
