An expression for half of a number can be represented mathematically as ( \frac{x}{2} ), where ( x ) is the original number. This indicates that the number is being divided by 2, resulting in its half. For example, if the number is 10, half of it would be ( \frac{10}{2} = 5 ).
You would add 8 - making the number 550. 550 divided by 10 is 55.

Because your calculator is broken. Seriously; 30 divided by half (0.5) is 60 and 60 + 10 = 70 So, 30 cut in half (30/2) is 15 but 30 DIVIDED BY half (30/0.5) is 60.
70: 30 divided by 1/2=60+10=70 trick: not 30 divided by 2

Half of 20 is 10. If you add 10 and 10, you will see that they make 20. Since they are both the same number and equal to 20, then 10 is half of 20.
