The sum of the digits of a 3- digit numbesi is 18. If the tens digit is the same as the unito digit but 3 less than the hundred digits find the number.
solve it , with sum
Answers
“The hundred’s digit is 1/3 the unit’s digit”
is the same as saying
“The unit’s digit is three times the hundred’s digit”
Let’s look at all you information in terms of h, the hundreds digit:
We assume:
Hundred’s digit = h
The ten’s digit is twice the hundred’s digit
The ten’s digit is twice h
Ten’s digit = 2h
The unit’s digit is three times the hundred’s digit
The unit’s digit is three times h
Unit’s digit = 3h
If you add up the digits of a three-digit number you get 18.
The sum of the three digits is 18
h + 2h + 3h= 18
What do you get when you add: 1h + 2h + 3h?
6h = 18
What do you get when you solve for h?
Divide both sides of the equation by 6
6h6=186
h = 3
I’ll let you finish from here.
What are the other two digits?
The ten’s digit is twice h
The unit’s digit is three times h
I hope it helps you.
