    yes A, is 4.8 inches for part B, can you write the ratios? give it a try.

    can you re-read the other post, and try to do that for part B ?

    not completely different. first, from the first sentence in the problem you should get this: 2 inches is to 25 miles

    \[\frac{ 2 }{ 25 }\]

    in part B, it asks about 1/4 of an inch is how many miles write 1/4 inch is to x

    almost. but the first ratio you wrote was 2 inches / 25 miles notice we have inches up top and miles in the bottom when you write 1/4 inches is to x miles, we want inches up top and miles in the bottom

    yes. with ratios, we set them equal to each other \[ \frac{2}{25}= \frac{1/4}{x} \] the "x miles" is in the bottom (as it should be), but it would be nicer if it were up top we can do that *if we flip* both sides

    \[ \frac{25}{2} = \frac{x}{1/4} \]

    it still looks a bit ugly, but we can "get rid of 1/4" by multiply top and bottom by 4

    in other words we do \[ \frac{x\cdot 4}{\frac{1}{4} \cdot 4} \]

    1/4 * 4 in the bottom simplifies to 1

    \[ \frac{25}{2} = \frac{x}{1/4} \\ \frac{25}{2} =4x\] I would divide both sides by 4 (to get x by itself)

    25/2 is 12.5 so you have 12.5 = 4x or 4x= 12.5 then divide both sides by 4 4x/4 = 12.5/4 x= 12.5/4
