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.
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.
30-40 because u multiply 15&20 by 2
One method is to divide 150 by 100 and then multiply the answer by 20, you will find the answer is 30
Given 20 and 50%, multiply 20 by 0.5, which equals 10. Given 70 and 30%, multiply 70 by 0.3, which equals 21. Or if you prefer, given 20 and 50%, multiply 2 by 5, which equals 10. Or if you prefer, given 70 and 30%, multiply 7 by 3, which equals 21.
20/30 times(multiply) 100 = 66.67%
Multiply .20 by 30, which should equal 6
10 explanation: from 60 to 30 you multiply by 1/2 from 30 to 20 you multiply by 2/3 from 20 to 15 you multiply by 3/4 from 15 to 12 you multiply by 4/5 from 12 to 10 you multiply by 5/6

1*10 = 10 2*10 = 20 3*10 = 30 3 cannot multiply to 10 or 20 but it can to 30. 2 can multiply to any of these. Therefore the least common multiple of 2,3 and 10 is 30.
% = per (cent) hundred.20% = 20/10020/100 * x/150Cross multiply 20 *150 = 3000100*x = 100x3000/100x = 30
One method is to divide 150 by 100 and then multiply the answer by 20, you will find the answer is 30
from 6 / 20 multiply both sides by 5 6 / 20 x 5 / 5 = 30 /100 Answer: 30%
Given 20 and 50%, multiply 20 by 0.5, which equals 10. Given 70 and 30%, multiply 70 by 0.3, which equals 21. Or if you prefer, given 20 and 50%, multiply 2 by 5, which equals 10. Or if you prefer, given 70 and 30%, multiply 7 by 3, which equals 21.
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
