One kilometer is about 0.62 mile. It is 12 kilometers from Noah's house to the ice skating rink. About how many miles is it from Noah's house to the ice skating rink?

Let's think about how we would get 12 kilometres from 1 kilometre. Multiply by 12, right? And if 1 km is equivalent to 0.62 miles, then multiplying that by 12 would get us the equivalent result in miles.

0.62*12=7.44

So, that would be 7.44 miles.

We can also do it with ratios

(1km : 0.62mi = 12km : xmi)

x = (0.62mi * 12km) / 1km, and we get the same result. Whichever works best for you.
