Answer:
168
Step-by-step explanation:
Windows calculator in programmer mode can convert this for you. If you want to do it by hand, each position in the number has a 'weight' as a power of 2, your value is:
2⁷+2⁵+2³ = 168
This is because there are ones at positions 3, 5 and 7, counting from the right and starting at 0.
