Answer 11

(a + 2/4 b) - (a - 1/10 b) + (a - 3/5 b)\[\left(\frac{1}{2} (2 a+b)\right)-\left(\frac{1}{10} (10 a-b)\right)+\left(\frac{1}{5} (5 a-3 b)\right) \]Multiply by 10\[10\left(\left(\frac{1}{2} (2 a+b)\right)-\left(\frac{1}{10} (10 a-b)\right)+\left(\frac{1}{5} (5 a-3 b)\right)\right)=10 a \]10a/10 = a
