Answer:
9. 4/25
10. Any decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number. Let me illustrate with an example. Hi there, Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers.
X=4
(X+20)/2 = 3x
Multiply everything by 2 to cancel out the 2; therefore, (x+20)= 6x
Now solve for x,
20= 6x-x
20= 5x
Divide everything by 5 to solve for x,
20\5 = 5x/5
4=x
