Question 911800
dividing a number by 2 is the same as muliplying a number by 1/2.


that's true.


when you multiply 2 fractions together, you multiply the numerators and then you multiply the denominators and your result is the new fraction.


for example:


1/2 * 3/5 = 1*3 divided by 2 * 5 = 3 / 10


likewise:


also, every number can be expressed as a fraction by dividing it by 1 since any number divided by 1 is equal to the same number.


example:


5 = 5/1


taking the above statements into considerations, if you have 1/2 * x, then it's equivalent to 1/2 * x/1 which you can then multiply together to get 1*x divided by 2*1 which results in x/2.


you get 1/2 * x and x/2 are equivalent.


if you use them on any number, the result will be the same.


example:


8/2 = 4


1/2 * 8 = 8/2 = 4
