Question

Please help me:

Convert each of the following from decimal form to the given base.

A) 65 to base seven
B) 2730 to base sixteen
C) covert CO2sixteen to base seven

Answer 1

65 in base 7: \(7^2=49\) so there is a \(1\) in the seven squared place
then \(65-49=16\) and there are 2 \(7\)'s in 16, to there is a \(2\) in the sevens place
then \(16-14=2\) so there is a \(2\) in the ones place
answer: \(122\)
