The product of two positive numbers is. 5/6 and their quotient is 15/8. Calculate the numbers.
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let "x" and y" be the two numbers.
We have
xy =
, (1) and
=
. (2)
Multiply (1) and (2) (both sdes). You will get
=
=
.
Hence, x = +/-
.
Next, divide (1) by (2) (both sides). You will get
=
:
=
=
.
Hence, y = +/-
.
Answer. There are two solutions: (x,y) = (
,
) and (x,y) = (
,
).
// We should exclude the second solution, since the numbers are negative.
