Answer:
1. already in standard form
2. already in standard form
3. 30/31
4. 7/9
5.-7/10
Step-by-step explanation:
a rational # a/b is in standard form when b is positive, and the only thing the two #s have in common is 1.
basically you have to find the biggest # that both the #'s can be divided by, then divide them. If the denominator is negative then multiple both the numbers by -1. If both the numbers are negative they will cancel out to be positive. Hope this helps.
