1/7 x 12/9 = 12/63 = 4/21
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.
Oh, what a lovely question! To find the average of those numbers, you simply add them all together and then divide by how many numbers there are. So, for 6, 7, and 8, you would add them (6 + 7 + 8 = 21) and then divide by 3 (since there are 3 numbers), giving you an average of 7.
Divide both numbers by 16
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.
1/7 x 12/9 = 12/63 = 4/21
If you want it simplified, divide both numbers by 3 (the GCF). 7 to 32
both numbers have a common factor of 7 divide each by 7: 21/28 = 3/4
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.
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.
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.
7 is because that is the highest number you can divide both numbers by.
3 & 7 (and of course, 1 and 21)
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.
1, 3, 7, 21.
You add the numbers, then divide the result by 3. In this case you divide by 3 because there are 3 numbers.
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.
