? how do you change a base 10 number to base 5
this is 6th grade middle school level....I am a perplexed paren who have been out of school for 20 years....please help
When we use base 10 to express a number, say 5472, we are doing so in powers of 10. That is
= 5x103 + 4x102 + 7x10 + 2
To express a number in base 5 notation you need to write it in powers of 5. Let me take 613 as an example. First I want to see how many digits I will need. To do this I calculate powers of 5
52 = 25
53 = 125
54 = 625
Start with the 53 digit. How many 125's are there in 613?
The remainder is 113 so how many 25's are there in 113?
The remainder is 13 so how many 5's are there in 13?
