Rewrite like this: \[\frac{4a^5 \dot\ 2b^2}{2a^4 \dot\ 7b^4}\]

do i just multiply accross?

Or you can work with each separately by rewriting like this: \[\frac{4}{2} \dot\ \frac{a^5}{a^4} \dot\ \frac{2}{7} \dot\ \frac{b^2}{b^4}\]

You already know how to reduce the numerical fractions.

You know that 4/2 = 2. You also know that 2/7 is already in simplest form and cannot be reduced any further

So for the numbers, you are just left with \[2 \times \frac{2}{7} = \frac{4}{7}\]

For the variables, you have to use this rule: \[\frac{a^y}{a^x} = a^{y  x}, y > x\] \[\frac{b^x}{b^y} = \frac{1}{b^{yx}}, x<y\]

So \[\frac{a^5}{a^4} = a^{5  4} = a^1 = a\] \[\frac{b^2}{b^4} = \frac{1}{b^{42}} = \frac{1}{b^2}\]
