The answer would be B.

To properly solve the answer you would have to leave \frac{2}{3} alone and change the division sign into multiplication. Then, do reciprocal of \frac{4}{5}.

In this case the person did not do the reciprocal of \frac{4}{5}.

So, the answer is B

In the division a/b, a is the dividend, and b is the divisor.

In this problem, 2/3 is the dividend, and 4/5 is the divisor.

She needed to multiply the dividend, 2/3, by the reciprocal of the divisor, 5/4.

Instead, she multiplied the dividend by the divisor without using the reciprocal.

Answer: second choice

I need help please.
pishuonlain [190]

Distributive property means that you have to multiply everything directly outside the parent hes to everything inside the parentheses. For this problem multiply 7 to the 9x and to the -9 like so:

7(9x) + 7(-9)

63x + (-63)

63x - 63

Look at image below if you are still confused

Hope this helped!
