My daughter is in sixth grade and got a different answer than her teacher's answer book. She came up with -1 7/10. I just got -7/10. My husband got 0.1. Her teacher says the answer is 1. Here is the problem and my solution.
1/2 * -3 / 5/4 + 3/5 - 1/10 = ?
I did this:
1/2 * -9/3 = -9/6 or -3/2
-3/2 / 5/4 = -3/2 * 4/5 = -12/10 or -6/5
-6/5 = 3/5 = -3/5
-3/5 - 1/10 = -6/10 - 1/10 = -7/10
What do you say?
