How do you divide fractions to twelfths?
1/7 x 12/9 = 12/63 = 4/21
How do you rss multiple numbers together to obtain the average?
Add the numbers together, then divide the result by the number of numbers that were added. For example, 4, 6, 9, and 2 = 21. Now divide 21 by 4 to get the average, which is 5.25.
What is the average of the numbers 6 7 and 8?
6 + 7 + 8 = 21 there are three numbers so divide by three 21/3 = 7
How do you simplify 32 16?
Divide both numbers by 16
How do you mulyiply and divide negative numbers by positive numbers?
1). First, ignore the signs. Just go ahead and multiply or divide the numbers as if they were both positive.Then, when you have that answer . . .2). If both of the original numbers had the same sign, then the answer is positive.If the original numbers had different signs, then the answer is negative.
How do you divide fractions to twelfths?
1/7 x 12/9 = 12/63 = 4/21
What the ratio 21 to 96?
If you want it simplified, divide both numbers by 3 (the GCF). 7 to 32
What is 21 over 28 simplified?
both numbers have a common factor of 7 divide each by 7: 21/28 = 3/4
How do you simplify the ratio 21 to 33?
1) You look for a common factor between the two numbers. Prime factorization can help here. 2) You divide both numbers by this factor. Three goes into both 21 and 33. 21 to 33 can be simplified to 7 to 11.
Why do you reduce?
How you reduce is that you take the two numbers lets say 15/21 and find the GCF of both numbers. In this case it's 3. Then you divide the two numbers by 3 until you can't divide no more and that's how you reduce : ).!
What is 2169 in simplest form?
assuming 2169 is meant to be 21/69 then divide both by 3 21/69 = 7/23 no further reduction possible as both 7 and 23 are prime numbers.
Could 7 be the greatest common factor of 21 and 35?
7 is because that is the highest number you can divide both numbers by.
What is the LCM of the numbers 14 and 21 mean?
The LCM of 14 and 21 is 42. What this means is that 42 is the smallest whole number such that both 14 and 21 divide into it (without remainder). Both 14 and 21 divide into 84, for example, so 84 is a common multiple. But 42 is smaller than 84 so 84 is not the least.
What numbers divide into 21 evenly?
3 & 7 (and of course, 1 and 21)
130 men and 105 women what is it as a ratio how do you work it out to find the answer?
Well, first put the two numbers side by side with the ratio symbol between them: 130:105 Then, divide both numbers by a number that will leave two WHOLE numbers 130 divided by 5: 105 divided by 5 = 26:21 Keep on doing this until you cannot find a number to divide both numbers by to get a whole number result. In this case, we can't divide the two numbers any more, so 26:21 is the answer.
What numbers divide 21evenly?
1, 3, 7, 21.
What is the average of 21 17 and 19?
You add the numbers, then divide the result by 3. In this case you divide by 3 because there are 3 numbers.
