Solutions
(a) 20% of x of 600
20/100*x = 600
1/5*x = 600
x = 600*5
x = 3000
(b) 12% of x is 480
12/100*x = 480
x = 480*100/12
x = 40*100
x = 4000
(c) 10% of x is 4 liters
10/100*x = 4
1/10*x = 4
x = 4*10
x = 40 liters
(d) 55% of x is 385 minutes
55/100*x = 385
11/20*x = 385
x = 385*20/11
x = 35*20
x = 700

Step-by-step explanation:
20% of x is 600
20/100 * x = 600
20x/100 = 600
x = 600*100/20
x = 3000
(b) 12% of x is 480
12/100 *x = 480
12x/100 = 480
x = 480*100/12
x = 4000
