If 2 proportions are equal:
we can cross multiply to get:
Numerator 1 Denominator 1
%3E
Numerator 2 Denominator 2 Numerator 1 * Denominator 2 %3E Denominator 1 * Numerator 2
Denominator 1 %3E | Numerator 1 * Denominator 2 |
Numerator 2 |
9x %3E | -8 * 81 |

9x %3E | -648 |
-61 |
9x %3E 10.622950819672
Because we have an inequality and we are dividing by a positive number, we keep the same sign %3E
