let h = the hundreds digit\
let t = the tens digit
let u = the units
:
Write an equation for each statement:
:
The tens digit of a three digit number is three times the units digit
t = 3u
and
the units digit is one fourth the hundreds digit.
u = .25h
or
h = 4u
If the sum of the three digit is 16,
h + t + u = 16
Replace t and h
3u + 4u + u = 16
8u = 16
u =16/8
u = 2
I'll let you find t and h, confirm that the 3 digits add up to 16
