Convert 12 inches to millimeters (to the nearest tenth).

I'll be happy to do math that I am assigned! Yay!

To figure this out, we must know the base comparisons. This just requires memorization, unfortunately.

$$1in=0.0254m$$

I happen to know that this is the base comparison. However, I'll have to do 2 conversions. One for the appropriate number of inches and one for meters to millimeters. Here it goes!

 $$\frac{1in}{0.0254m}=\frac{12in}{xm}$$ This is a proportion. Solve by cross multiplying. $$x=12*0.0254=0.3048m$$ Therefore, this shows that 12 inches is equivalent to 0.3048 meters. Now, we must convert to millimeters. $$\frac{1000mm}{1m}=\frac{ymm}{0.3048m}$$ Cross multiply a second time. $$y=0.3048*1000=304.8mm$$

Bam! Done! 12 inches = 304.8 millimeters!
