Answer :

600 = 100%
 x   = 40%

Cross multiply

100x = 600 * 40
100x = 24000
     x = 24000
             100
     x = 240

S = 240
To get 40% of 600 you have to follow these steps.
1. Change the percent into a decimal; which in this case would be 0.40
2. Then multiply 0.40 times 600.
3. Then Solve.
