How do you convert 0.36 (repeating 6) to a fraction?

=411

Le x=0.363636363636

Now as there are two digits repeating immediately after decimal point, we multiply above by 100 and get

100x=36.363636363636

Now subtracting first equation from second we get

99x=36 and hence x=3699=9×49×11=411

correct

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
