Hi, my name is Marija, and today I'm gonna show you how to solve measurement problems. Many measurement problems are solved through conversions. So, if you are asked how many inches are in 3 feet, then the first thing that you need to know is what is the conversion rate between the inches and feet? So, if you know that, we know that 1 foot is equivalent to 12 inches. So you can take the ratio that you know, the relationship that you know, 1 to 12, and you set it up as a ratio. Then we're gonna set this up to be a proportion. And on the other side what's important when you're converting between measurements is that whatever measurement you had in the numerator on the left you have to have the same one on the right. So, am I given the feet? Yes I am, it's three, so that three is gonna go right here in the numerator. I'm not given the inches, I'm asked for the inches, so whenever you don't know something, you write a variable. So now that we've set up the proportion correctly, we can cross multiply and find out what our conversion is. So x times 1 is just x, and 12 times 3 is 36, meaning that 3 feet are equivalent to 36 inches.
