You add 20
4 add 12 = 16 and that is an square number
12 more than 19 means that you add 12 to 19 and you get 31.
30 divided by 12 plus 10 = 12 1/2 (12.5)
12 plus 63 is 75.
So the mix number can be 2 4/6 (2 is the whole number. 4 is the Numinator and the 6 is the denominator) So Then you multiply the whole number (2) by the denominator(6) Once you multiply your answer should be 12. Then With the answer your got (12) you add 12 plus the Numinator (4) 12+4=16 Then your answer in fraction is 16/6
The answer is 120. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
To maintain balance in the equation, you should also add -5 to the right side.
The answer is 144. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
The next number in the sequence is 9. The rule is to add 2, then subtract 1, add 2, subtract 1, and so on.
First, add two plus ten together. That number is 12. Then do the opposite function that you did earlier, which would be multiplying by 3. 12 times 3 is 36, so the answer is 36.
They add up to 39
5/6 plus 1/4 you should find a common denominator and then figure it out 12 is the lcd (lowest common denominator) multiply the numerator and denominator by the same number so the denominator equals 12 for the first it's 2 and the second 3 10/12 3/12 add it you get 13/12 or 1 and 1/12
