Divide 30 by 12 and add 10 What is the answer?

Divide 30 by what? 10? If so, than the answer is 13. 30/10 = 3, 3 +10 = 13

The answer is 70. If you divide 30 by 0.5 you get 60 then add 10 you get 70. The trick here is that people read it as 'divide 30 IN half' and end up with a total of 25.

12 +12+6=30 30/3=10 to find the average of something you add up the values and divide the total by the number of values you had

70 I got this: 30/2+10=25

30 divided by 5 = 6 + 10 = 16

30/2=15 15+10=25

30:2=15 15+10=25 so it's 25 Answer A different aproach would be to do the following: 30 : 1/2 (a half) = 60 + 10 = 70. Half of 30 is 15 so divide 30 by 15 and you get 2 + 10= 12!

30/(1/2) + 10 = 30x2 + 10 = 60 + 10 = 70.

Half is the same thing as .5 so you divide 30 by .5 and you get 60 then you add 10 so it is 70. TADA!!!

Add all numbers and divide it by the amount of numbers. E.g. Calculate the mean: 12, 22, 10, 30 12+22+10+30=74 74/4=18,5 mean=18,5

30/0.5=60 60+10=70

30 divided by .5 plus 10 equals 70 70

To price anything by the slice: Take the item cost as a whole and add 30%, then divide by the total number of slices. (Ex - Cake cost you $10. Add 30% = $13 divide by 12 slices and your price per slice is 1.08.)

66 if you meant 30 divided by 2 plus 10% it is 16.5

The answer is 70 (30 / 0.5 = 60, 60 + 10 = 70)

To find the mean you first have to add up all the numbers then you divide it by how many numbers you have and you got the mean. Example: 12+13+5=30 30/3=10 10 is the mean

70 It is asking to divide by 1/2 not divide by 2 70 because 30 divided by half (0.5) is really multiplying it by 2. (30 X 2 is 60 + 10 is 70) Then plus ten is 70. Wouldn't you divide 30 by half (15)??????

Seventy. 30 / .5 = 60; 60 + 10 = 70.

10 multiply by 3 30 divide by 2 15 add 1 16 repeat 16 multiply by 3 48 divide by 2 24 add 1 25 repeat

Add the 4 numbers and divide by 4. answer = 100/4 = 25

25 Add the items together 10 + 20 + 30 + 40 = 100 Divide the total by the number of items 100 ÷ 4 = 25

30. (Add them all together, then divide by 5, the number of items.)

6. factors of 12 are 1, 2, 3, 4, 6, and 12. factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.

Add the two numbers together and then divide by two. Assume the two number is 10 and 20. Add them together (30) and divide by 2 (15).

Any of them. To get 50 to 30 you could... subtract 20 add -20 divide by 5/3 multiply by 3/5
