Johnetta simplified 7/9-3/8 ; her work is shown below. Identify where she made her error.

Original division problem 7/9-3/8:

Step 1: 7/9*3/8

Step 2: \(\frac{7 * 3}{9 * 8}\)

Step 3: 21/72

Step 4: 7/24

I feel like step one is wrong.

The problem was,

\(\frac{7}{9}-\frac{3}{8} \)

and step one multiplys them, which is incorrect.

The step reads the problem wrong.

Step 4 is correct however.

21/72 simplifys to

7/24.

Yes, because when you divide, you flip the fraction.

You need to flip the fraction in step one, which it doesn't.
