Triangle DEF and Triangle GHI are similar. If DE, EF, DF, and GH are 12 inches, 14 inches, 15 inches, and 14.8 inches respectively, find HI to the nearest tenth.

DE:GH = 12:14.8 = 0.81
EF:HI = 14:?
? = 14/0.81 or 14*14.8/12 = 17.267.

HI/14.8 = 14/12
HI = 14.8*14/12 = 17.3 inches

ratio = 14.8 / 12 = 1.23333
EF = HI, EF = 14
Thus HI = 14 * (14.8/12) = 17.3

GH / DE = 14.8 / 12
HI / EF = 14.8 / 12
HI = EF x 14.8 / 12
HI = 14 x 14.8 / 12
HI = 17.3 inches (to 1 decimal place)
