Answer:
12, -6.4, 0.75
Explanation:
I don't know if the question is to add them together or something but here's how I solved them.
Step 1: Use order of operations to solve 3 / 5 - 7
3 / 5 - 7
0.6 - 7
7 - 0.6 = 6.4
-6.4
Step 2: Divide 3/4
3 / 4 = 0.75 (A good way to think of it in fourths is to think of if I have three quarters, how much money do I have?)
