Answer:
6 is 30 percent of 20 STEP 1 6 = 30% × Y 
 
STEP 2 6 = 
30 
100 
× Y 
 
Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at: 
 
STEP 3 Y = 6 × 
100 
30 
 
STEP 4 Y = 6 × 100 ÷ 30 
 
STEP 5 Y = 20 
 
Finally, we have found the value of Y which is 20 and that is our answer. 
 
You can easily calculate a similar type of calculation by using any regular calculator, simply enter 6 × 100 ÷ 30 and you will get your answer which is 20
