14 is added to 2\3 of a number. The result is 1 whole number 1\4 times the
original number.find the numbers.
That is not grammatical. Something is wrong or missing.
Tutor Ikleyn assumed "1 whole number 1\4" meant "1 PLUS 1/4" or 5/4.
IOW, she interpreted it to mean this:
14 is added to 2/3 of a number. The result is
times the original number. Find the number.
With her interpretation, she obtained the answer as 24.
Notice that the student wrote "find the numbers" (plural) but she
only found only one number, and changed "numbers" to "number".
============================
Tutor josgarithmetic(39489) interpreted it as though the "1\4 times" was
reversed and should be "times 1/4". He interpreted it as:
14 is added to 2/3 of a number. The result is 1 whole number times 1/4 the
original number. Find the numbers.
He gave an example where the original number is -84 and the whole number is 2.
There are 6 solutions in all for his interpretation:
(-84,2), (-21,0), (6,12), (24,5), (42,4), (168,3)
============================
I will assume that the student inadvertently omitted the word PLUS.
So I'll do it with this interpretation:
14 is added to 2/3 of a number. The result is 1 whole number PLUS 1/4 times
the original number. Find the numbers.
Let x be the original number and let y be the 1 whole number.
Solve for y, which must be a whole number:
Since y must be a whole number, x must be a multiple of 12
to cancel the denominator in the first term.
Let x = 12k
Whole numbers are non-negative integers, so
k is an integer, so
So the infinite set of solutions is
{ (12k, 5k+14) | k > -2 }.
Some examples of solutions are:
(-24,4), (-12,9), (0,14), (12,19), (24,24), (36,29), (48,34), ...
