What two numbers add up to 21 and multiply 30?
51
How does 9 3 and 7 make 30?
One way is to multiply 3 and 7 in order to get 21 and then add 9 to 21 in order to get 30.
What percent is 21 out of 30?
To find the percent that a number, x, is out of another number, y, divide x by y and multiply by 100. So (21/30)*100 = 70, which means that 21 is 70% of 30.
What is 30 Percent of 70?
30% is 0.30 so, 0.30 x 70 = 2100 move the decimal to the left 2 times and get 21 and 21 is your answer!
How do you know that the fraction 21 over 30 is larger than 2 over 3?
You can't accurately compare fractions if they don't have a common denominator. In other words, the bottom numbers of both fractions have to be the same. To change that, you have to find the LCD, or least common denominator (the smallest number both bottom numbers multiply evenly into.) In this case, the LCD is 30, since 3 is a factor of 30. Since 10 x 3 =30, we have to multiply the top number (or numerator) by 10 also. Here's what the process looks like: 21/30 > 2/3 (original problem) 21/30 > ?/30 (find the LCD) 21/30 > 20/30 (multiply the numerator by the same number as the denominator) 21/30 > 20/30 (final answer) So there you have it. 21 is larger than 20, therefore 21/30 is larger than 2/3.
How do you find the percent of a number when the percent and number both ends with a zero?
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.
What is 21 percent of 70?
To find 21 percent of a number, multiply the number by 0.21. In this instance, 0.21 x 70 = 14.7. Therefore, 21 percent of 70 is equal to 14.7.
