Say you had to turn 9/30 in to twentieths. First you find the common denominator of 30 and 20 (the lowest thing that both of them multiply into) and then multiply the first number into it. So 9/30 would turn into 18/60, which you can then divide by 3 to get twentieths, which is 6/20.
To find 20 percent of a number, multiply the number by 0.2. In this instance, 0.2 x 30 = 6. Therefore, 20 percent of 30 is equal to 6.
The only square number between 20 and 30 is 25.
The fastest way to take 20 percent off a number is to multiply the original number by 0.8 20% of 30 is 6. 30 - 6 = 24 30 x 0.8 = 24
It is 11/30.
20 is between 10 and 30.
Let the unknown number be n.Then 20 + n = 30 : Subtract 20 from both sides gives :-20 - 20 + n = 30 - 20 : n = 10
It is: (20+30)/2 = 25
To find 20 percent of a number, multiply the number by 0.2. In this instance, 0.2 x 30 = 6. Therefore, 20 percent of 30 is equal to 6.
20 is 30% of 66.67

10/1 or 20/2 If you would like the number ten to be in the form of a fraction, it could be 10/1 or 20/2 or 30/3 etc.
30*20=600
30
The smallest number into which both 20 and 30 will divide evenly is 60.
The gcf of 20 and 30 means the greatest common factor. You can do this my dividing 20 and 30 by the same number. Eventually, you will get 10, no other number is greater than 10. 20/10 = 2 and 30/10 = 3. So your answer will be 10.
30/7 as a mixed number is 4 2/7.
