2. They're trying to trick you here.....hoping that you will choose 18 : 555.....unfortunately....that's not correct...we need to compare like units.... namely, feet.....18 in  = 1.5 ft....so.....

1.5 : 555  = 1 : x        set up as two fractions

1.5 / 555 =  1 / x     cross-multiply

1.5x   =  555    divide both sides by 1.5

x = 370

So....   1 : 370    is correct

3.   Δ HTM  is similar  to Δ MTA  is similar to  Δ HMA
