Question

ten inches of heavy, wet snow are equivalent to three inches of rain. Estimate the water content in 17 inches of heavy, wet snow.

Answer 1

Estimate ... 10 in snow to 3 in rain...20 in snow to 6 in....so my estimate would be a little less then 6 inches.

actual answer ...
10/3 = 17/x (10 in snow to 3 in rain = 17 in snow to x in rain)cross multiply
10x = (17)(3)
10x = 51
10x/10 = 51/10
x = 5.1 in of rain.

check...
10/3 = 17/5.1 (cross multiply)
(10)(5.1) = (3)(17)
51 = 51 (correct)
