Question

A wood stove burns 4 same sized logs in 2 hours how many logs does the stove burn in 8 hours

Answer 1

By using the information you have, you can use make a proportion to solve this. You burn 4 logs in 2 hours or 4/2. You are comparing this to your unknown number, x, over 8 hours. So it looks like this 4/2 = x/8. You read it as four logs in two hours is x logs in eight hours. To solve you cross multiply. You do 2 times x and 4 times eight. That would be 2x= 32. Your goal is getting x alone, so divide each side by 2. Your answer is x= 16 logs in eight hours. You can solve this different and maybe easier ways but this is the best way if you want to get used to going this in algebra. Hope that helps! :)

Answer 2

16 because 2 divided by 8 = 4 and 4×4 =16
