Question 1 Report

if \(y = 23_{\mathit{five}} + 101_{\mathit{three}}\) find y leaving your answer in base two

Answer Details
First we convert the numbers to base ten
23 f i v e = 2 x 51 + 3 x 50
= 10 + 3 = 13
101 f i v e  = (1 x 32) + (0 x 31) + (1 x 30)
= 9 + 0 + 1 = 10
So, y = 13 + 10 = 23
To convert 23 to base 2 (as in the diagram above)
y = 23
= 10111
