Answer:
Step-by-step explanation:
let the numbers at unit,ten and hundred place be x,y,z respectively,then number=100z+10y+x
also x=4z
y=z+5
and x+y+z=17
4z+z+5+z=17
6z=17-5=12
z=2
y=2+5=7
x=2×4=8
number=100×2+10×7+8=278
X is 9 over 2! If the question requires a decimal point, put 9/2 into the calculator!
