Answer:
7
10
Explanation:
The first step is to make sure that the denominators are the same. In this case, they aren't. You need to find the least common factor(LCF).
The LCF for 10 and 5 is 10. To get 10, multiply 5 and 1 times 2.
9 - 1 ×2 = 9 - 2
10 5×2 10 10
Now, subtract the numerators. The denominators remain the same, but if possible, simplify them.
9 - 2 = 7
10 10 10
