Convert the decimal 0.6333… to a fraction and classify it as either rational or irrational. a. 57⁄9, irrational b. 57⁄90, rational c. 63⁄90, rational d. 63⁄99, rational

answer B

We assume        x=  0.6333

100x = 63.3333

  10x=  6.333  33               (subtract it )

----------------------------

 90x = 57 ( divide by 90 on both sides)

So x=

Answer :

When we can write a number in fraction form then it is a rational number.

We converted the  decimal number into a fraction so it is rational

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

i believe the answer is c.
