Remark
You could convert base two to base 10 and then convert base 10 to base 8. That's the long way. The procedure below is the short way.
Step One
Write the base 2 number in groups of 3 starting from the right and going left
11 100 111
Step Two
Convert the base 2 numbers in groups of 3 to base 8. The largest result will be a 7
11 = 2*1 + 1 = 2 + 1 = 3
100 = 1*2^2 = 4
111 = 1*2^2 + 1*2 + 1 = 7
Step Three
Read the answer going down.
347 is the answer
Answer
347(8) = C
Answer
101.76(i think)
Explanation
First you would change the percentage to a decimal which would be 0.25. Multiply 0.25 x 128 = 32
Subtract 32 from 128 to get 96
96 x 0.06 = 5.76
5.76+ 96 = 101.76

Answer:
14/5 or 2 4/5
Step-by-step explanation:
7 3/5 = 38/5
4 4/5 = 24/5
38/5 - 24/5 = 14/5 = 2 4/5
