The Statements which are true are;
- Choice B; Subtraction and Addition are INVERSE operations.
- Choice D; Multiplication and Division are INVERSE operations.
Inverse Operations:
Operations said to be inverse if both operations are complementary.
- <em>On this note, when a number x is added to a given number y, we get a number z. Also, when we add x back to the number z; we get number y back.</em>
- <em>Similarly, when we multiply a number, x by y; we get z. When z is then divided by y; we get the number x back.</em>
Ultimately,
- Multiplication and Division are INVERSE operations.
- Addition and Multiplication are INVERSE operations.

The steps for dividing fractions are:
Keep
Flip
Change
As in, keep the first fraction the same (we can write 7 as 7/1 to make it a fraction), flip the second fraction upside down, and then change the division symbol to a multiplication symbol. This gives you:
7/1 × 5/6
And to multiply fractions, you multiply across, which means that you do (7 × 5 = 35)/(1 × 6 = 6). Your answer, therefore, is 35/6, or, as a mixed number, 5 5/6. I hope this helps!
Percent change is
(New - old) / old
50 - 75 / 75
25 / 75 = .33333333....
To convert to a percent, multiply by 100
Percent decrease = 33.33%
Answer:
A) multiplication
Explanation:
is a=b, then xa=xb, then the two are equal by the property of multiplication.
