95% means 95ml of every 100 is alcohol. So the answer is 228ml (take away 1/20, i.e. 12ml)
x+y = 240 0.06x + 0.12y =240(0.07) = 16.8 0.06x + 0.12(240 - x) = 16.8 0.06x + 28.8 - 0.12x = 16.8 -0.06x = -12 x = 200.......6% solution y = 40........12% solution

W-V percent concentration g/mL = 1.20g/240mL = 0.005 g/mL percent
240/100
3.5 percent of 240 = 8.43.5% of 240= 3.5% * 240= 0.035 * 240= 8.4
64 percent of 375 is 240.
To convert a fraction to percent multiply by 100 % 36/240 × 100% = 15% → 36 is 15% of 240.
150 pages 37.5% of 240 is 90 240-90=150
