$a) 1111_{(2)} =1\cdot2^{3} +1\cdot2^{2} +1\cdot2^{1} +1\cdot2^{0} = 8+4+2+1=15_{(10)}$

$b) 10001_{(2)} =1\cdot2^{4} +0\cdot2^{3} +0\cdot2^{2} +0\cdot2^{1} +1\cdot2^{0} = 16 +0+0+0+1=17_{(10)}$

$c) 101011_{(2)} =1\cdot2^{5}+ 0\cdot2^{4} +1\cdot2^{3} +0\cdot2^{2} +1\cdot2^{1} +1\cdot2^{0} = 32 +0+8 +0+2+1=43_{(10)}$

$d) 11111101_{(2)} =1\cdot2^{7}+1\cdot2^{6}+ 1\cdot2^{5}+ 1\cdot2^{4} +1\cdot2^{3} +1\cdot2^{2} +0\cdot2^{1} +1\cdot2^{0} = \\ =128+64+32+16+8+4+0+1=253_{(10)}$
