Question

The product of a fraction and 7 is greater than 7. The denominator of the fraction is 7. What is true about the numerator? (This may not be understandable due to a typo in the question. Sorry if you don't understand a single thing. I'll tell my teacher about this.)

It is greater than 7.
It is less than 7.
It is equal to 7.
It is equal to 0.

Answer 1

The product in the numerator is -20 + 10i.

The product in the denominator is 50.

Answer 2

The product of a fraction and 7 is greater than 7, if fraction i a/b then (a/b)*7>7
The denominator 7 means (a/7), so we can rewrite (a/b)*7>7 as
(a/7)*7>7, from this inequality we get
a>7,

so the numerator is greater than 7
