9/10 equals 0.9 , 2/7 equals about 0.28 . So 0.9 - 0.28 = 0.62 if you need .62 in a fraction it's 31/50
No, they are not equivalent. The first term, -4 1/2 equals 4 whole units and one half unit. All negative. So it’s like you have someone 4 and 1/2 dollars.
The second term, (-4)1/2 means multiplying -4 times 1/2. Doing the multiplication for this gives you -4/2. Solving the division here is -2. It’s taking away 1/2 dollar 4 times.
I hope this helped. Happy to answer any questions you have.

Answer: Yes, 4-6 is the same as 4 + (-6).
Step-by-step explanation:
