Question 636229
<font face="Times New Roman" size="+2">


Could be one of two things.  First let *[tex \LARGE x] represent "a number".  3 times "a number" is then *[tex \LARGE 3x].  "is" means "="  A quotient is the result of a division, but "the quotient of 10 and 3 times a number" is ambiguous as to which is the divisor and which is the dividend, hence the answer is either:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{10}{3x}\ =\ 21]


or


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{3x}{10}\ =\ 21]


In fact, there is a third possibility:  "the quotient of 10 and 3 times a number" can also be interpreted as "(the quotient of 10 and 3) times a number" where 3 (rather than 3x) is the divisor, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{10}{3}x\ =\ 21]

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
