A jar can hold 3/4 of a pound of flour. Austin empties 1/2 of a pound of flour into the jar. What fraction of the jar is filled? Enter your answer in numerical form please don't answer wrong to get points if ur answering wrong and you know its wrong just put a letter and it has to be in numerical form examples 1 8 9 5 any number not a fraction

66% or 0.66

Step-by-step explanation:

3/4 = 75% or 0.75

1/2 = 50% or 0.50

If austin puts in 1/2 of flour into the jar = 2/3 is filled since the jar can only hold 3/4 of flour.

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".
