I think diagram of number D show the inverse of R[X]
3/4 is the simplified version of 6/8. How I got this is I know that 4 goes into 8 twice so you multiply by 2. Whatever you do to the bottom you do to the top so you will get 6/8.
The answer is 358 but i cant use the number line in this case.
0.2 is the correct answer. All you have to do is divide 1 by 5 to get 0.2
The 8 is in the ones place.
The 1 is in the tenths place.
The 3 is in the hundredths place.
The 9 is in the thousandths place.
hope it helps!
