Step-by-step explanation:

The first step in simplifying the expression of the square root of 50 involves finding factors of 50. This just means we are trying to find two whole numbers that, when multiplied, equal 50. Since 50 is an even number, 2 is going to be a factor, and so we can rewrite 50 as 2 times 25.

12 x 1/2
How do I solve that, and what’s the answer?

Answers

Answer:

The answer is 6

Step-by-step explanation:

12 divided by 2 is 6. If you have a fraction of 1/2, then its half of it. 6 is half of 12. :)

Answer: 6

Explanation:

You can multiply the numerator by the numerator and the denominator by the denominator.

The numerator of 12 is 12 and denominator of 12 is 1.

[tex]\frac{12}{1} *\frac{1}{2}=\frac{12}{2}[/tex]

Simplify this fraction and you get 6 over 1 or just 6.

You can also use common sense (not really).

You probably know that 1/2 is one half. To find half of something, you would normally divide by 2. 12 divided by 2 is 6.
