Which symbol can be used to correctly compare the two fractions?

<span> The real question you need to solve is "Is 1/4 greater than, equal, or less than 15/100?" At first glance it's hard to determine how they relate to each other. So first make both fractions use the same denominator. The easiest way to do this is multiply both the numerator and denominator of each fraction by the denominator of the other fraction. So 1/4 * 100/100 = 100/400 and 15/100 * 4/4 = 60/400 Now ask yourself "Is 100/400 greater than, equal, or less than 60/400?" and the answer is pretty obvious. 100/400 > 60/400. So the answer is ">".</span>

.divide the problem.

Answer:

$x - 2x - 15 \: divided \: by \: x - 3$

according to the above x²-2x-15 divided by the number below x-3 first I cancel out the x
$x - 2x - 15 \: divided \: by \: - 3$
the we solve the next x-5 divided by x²-9 then as usual rule out the x
$- 5 \: divided \: by \: x - 9$
now we only have x-2x-15 divided by-3 divided by-5÷x-9 now our next step is to again single the equations out
$x - 2x - 15 \: divided \: by \: - 3 \: lets \: rue \\s \: rule \: out \: - 3 \: and \: 15 \: giving \: us \: x - 2x - 5$
now the next -5 divided by x-9 here there's nothing to rule out therefore the sign "÷" is changed to "×" cancel out the -5 and therefore we have
$x - 2x = x - 9 \: as \: final \: answer$
