(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

LCD of 5/2x and 7/5x3y

2. Relevant equations

Lowest common denominator is also lowest common multiple:

(2)(x)

(5)(x)(3)(y) =

(10)(x)(3)(y)

I figured, the lowest common multiple of 2x and 5x3y is 10x3y. For some reason, my book shows the answer as 10x^2(y)!

3. The attempt at a solution

At this point, I don't know why I didn't come up with the same solution as the book.

This is from the Pre-Algebra text "Preparation for Algebra" Nanney/Cable. I bought this from my college to brush up on a lot of fundamental skills I'd forgotten and this was an exercise in the beginning of the book. Is it a typo or am I just going crazy?
