Learning target #1: i can write equivalent fractions with different denominators.

equivalent fractions have
value but look

lowest terms: when the numerator and denominator of a fraction can only be divided

ratio: a comparison
quantities by division (a

proportion:
ratios

cross products: products of
of one fraction and the denominator of the other

Same value but look different

Step-by-step explanation:

3/4 x 2/2 = 6/8  

2/3 x 4/4 = 8/12

both of 6/8 is equivalent to 3/4

8/12 is equivalent to 2/3

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".
