10/100 * 20 = 2
20 over 10 is a whole number: 2
The answer is 10. 3 x 10 = 30 30 - 10 = 20
10
10
10/100 * 20 = 2
10 x 20 = 200
The only composite factor of 10 is 10. The composite factors of 20 are 4, 10, 20
10. Let us assume x is the number. x * (20/100) = 2 x * 20 = 200 x = 200/20 = 10 2 is 20% of 10.
20 is already rounded to the nearest 10.
22 + 8 - 10 = 20 Therefore, the number he is thinking of is 22.
20
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.
