Here,
We can write $$\frac{n * 10^3}{10^5} = \frac{n}{10^2} = \frac{105.873}{10^2} = 1.05873$$

SO QTY A > QTY B

Let's first see what needs to happen for the two quantities to be EQUAL

That is, we want $$\frac{n * 10^3}{10^5}$$ and $$1$$ to be EQUAL

We get: $$\frac{n * 10^3}{10^5}=1$$

Multiply both sides by $$10^5$$ to get: $$(n)(10^3)=10^5$$

Divide both sides by $$10^3$$ to get: $$(n)=\frac{10^5}{10^3}=10^2=100$$

So, if n equals 100, then the two quantities are EQUAL

Since n actually equals 105.873, we know that Quantity A must be greater than Quantity B

Cheers,
Brent
