If 50 percent of Q is 20 percent of P, then P is what percent of Q

P is 250% of Q

Step-by-step explanation:

50/100 Q  =   20/100P            Multiply both sides by 100

50Q = 20 P                              Divide by 20

50/20 Q = P

2.5 Q = P

So P is 2.5 times the size of Q.

2.5 as a percent is 250 %
