Draw a model to show a fraction that is equivalent to 1/3 and a fraction that is not equivalent to 1/3

is equivalent to

not equivalent to

Step-by-step explanation:

In a bag there are 9 marbles. A boy paint 3 of them and wrote numbers on 2 marbles.

Then the fraction of marbles painted to the total marbles=

Here, is equivalent to

The fraction of marbles which have number on them to the total marbles

which is not equivalent to

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
