How can I rewrite this statement for my math class: "The war funding bill...passed this week, but with three times fewer Democrats voting for it than did the last year.

To rewrite this statement for your math class, you can use the concept of ratios to convey the same information in a more precise way. Here's one possible way to rephrase the statement:

"The war funding bill...passed this week, but the number of Democrats voting for it was one-third of the number that voted for it last year."

In this revised statement, we use the concept of ratios to express the comparison. Specifically, we state that the number of Democrats voting this year was one-third (or three times fewer) than the number of Democrats voting last year.
