melania walked her dog 2 1 / 5 miles. cqthy walked her dog 1 3/4 times as far as melania did. how many more miles did cathy walk her dog

Let's set this equation up to make this easier.

melanie = 2 1/5 miles walked

cathy = 1 3/4 more times than melanie.

when an equation says the word, more than this means adding. when it says less than this means subtraction. when it says times (in this question) then multiply.

so, if cathy walked 1 3/4 more times than melanie what we would do is multiply 1 3/4 to what melanie was walking. so 2 1/5 times 1 3/4 which equals 3.85.

so overall, cathy walked 3.85 more miles than melanie.
