What percent is 60 of 150? answer choices 2.5% 35% 40% 90%

Hello from MrBillDoesMath!  

  40%

Discussion:

Let's ask an easier question. What is 1/2 or 50% of the number 150?. It's 75. Since 75 is larger than the problem's 60 we need to look for a slightly smaller percentage than 50%. The choice of 40% seems evident.

Another approach:  

60  =  (x/100) 150              

so  x = (60/150) * 100 = 40 %

you can't solve x because it is 2 linear equation and you only have one equation
