Rice Ratios… GED Math in the Kitchen?

I’m a guy, right? So you know I don’t cook. Yeah, yeah, I got ketchup in my fridge, that’s about it. But Maria came all up in here tryin’ to teach me to make somethin’ to eat. Okay, yeah, a guy’s gotta eat.

Well, she taught me a quick and easy way to make some rice in the microwave. Cheap way to eat. She gave me a bunch of measurements, but I don’t have no measuring cups. So she put it in terms of a ratio… you gotta have a 1:2 ratio of rice to water.

Well, I’ve got a coffee mug to measure stuff with, that’s it. Here’s the question…

I’ve got 1-1/2 coffee mugs worth of rice. How much water do I got to have to cook this stuff? Does the 1:2 ratio give me enough information?
