The quickest way for converting small numbers like this to binary would probably be to find the closest power of 2, then add/subtract intermediate powers of 2 as needed.
Converting 8 is immediate, since it's already a power of 2:
![8=2^3\implies 8_{10}=1000_2](https://tex.z-dn.net/?f=8%3D2%5E3%5Cimplies%208_%7B10%7D%3D1000_2)
Converting 15 and 17 is also pretty easy if you're familiar with the rules of arithmetic in binary.
![15=16-1=2^4-2^0\implies 15_{10}=16_{10}-1_{10}=10000_2-1_2=1111_2](https://tex.z-dn.net/?f=15%3D16-1%3D2%5E4-2%5E0%5Cimplies%2015_%7B10%7D%3D16_%7B10%7D-1_%7B10%7D%3D10000_2-1_2%3D1111_2)
Answer:
5
Step-by-step explanation:
Convert the element to fraction:
/ ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
Switch the division to multipl:
2/1 * 2/5
Cross multiply:
2 is elimiated and 1 and 5 remain.
Answer is 1/5 which is 5.
Answer:
Step-by-step explanation: l = 5 + w
p = 168
...
p = 2l + 2w
168 = 2(5+w) + 2w
168 = 10 + 2w + 2w
168 - 10 = 4w
158 = 4w
1 = 5 + 39.5
