What is the ratio of the sum of the first 7 even integers to the sum of the first 4 odd integers?

Hi there.

2 + 4 + 6 + 8 + 10 + 12 + 14 = 56

1 + 3 + 5 + 7 = 16

So far we have 56:16. We can simplify this by using division. These two both divide by 8, so we'll do that.

Simplified, we get a ratio of 7:2.
