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.
The answer will depend on whether the number is 0.717171... or 0.711111...
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.

There are questions, or there is qs
erhh.. quick silver
None in English, if you mean paired Qs.
In the construction industry, what is the role of a QS??

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!'.

If no Ls are Qs then the converse is true that no Qs are Ls. If all Qs are Js, then at least some Js are Qs. Therefore, at least some Js are not Ls. You cannot conclude that some Js are Ls, however. It could be that all Js are not Ls. This cannot be concluded from the information given.
