Yes: 2/10 = (2x1)/(2x5) = 1/5
No
one over two
put it over some power of ten(the one above it) and simplify.
Divide both numbers by ten. 5/13
A half = 1 over two = 1/2
If you mean (nine over ten) times two the answer is 6 over 5 If you mean nine over (ten times two) the answer is 3 over 10
divide it by two and ypu should get 12 over 50
Yup... 5 over 12 is the same as 10 over 24, because when you half ten you get 5, and half 24 you get 12.
You can't simplify that any further. 3 and 10 don't have any common factors.

You divide them by two so 22/32 becomes 11/16 and then you cannot simplify them anymore.
