D-t: 50. what is d an t to equal 50

Well lets find the value of our dividend base!
So we have 30 as the divisor~
We know the dividend is a 3 digit number which is obviously the least.
And we know about the remainder of 8.
We have to find the least number that can be divided with 30 so keep multiplying 30 until you find your least number.
30 * 1 = 30
30 * 2 = 60
30 * 3 = 90
30 * 4 = 120
So now we have 120 which is the least 3 digit number that can be divided by 30.
All we have to do now is add 8 as the remainder and we should be good!
120 + 8 = 128
Our remainder is left to be 8!
