Ratio is 100:1

Explanation:

From hydraulic press formulas;

(F1/A1) = (F2/A2)

Applying this to the question, we can say that Force on slave cylinder (Fs) = F1 while Force on master cylinder (Fm) = F2 and their respective Areas as As and Am.

Now plugging it into the equation to obtain;

Fs/As = Fm/Am

Now, the question says the hydraulic system is designed to exert a force 100 times as big as the one put into it, thus;

Fs = 100 Fm

And so from the equation earlier, rearranging, we have,

Fs/Fm = As/Am. So, 100Fm/Fm = As/Am

So, Fm will cancel out and we have;

As/Am = 100/1

Thus, the ratio of the area of the slave cylinder to the master cylinder is 100:1
