Question

1) division by zero is 2) name the property of addition used in 1/2019+1/2020=1/2020+1/2019 3) the multiplicative inverse of -a/b is 4) the periodicity of the decimal form of 1 by 7 is​

Answer 1

Answer:

1)not defined

2)commutative property under addition in rational numbers

3)-b/a

4)periodicity 6

Answer 2

Answer:

1) Undefined

2) Comutative property

3) b/-a

Step-by-step explanation:

1) The answer is undefined because if we multiply any number by 0 it would be zero because multiplying means multiple addition but if we take something 0 times we would get 0.

2) The property used here is commutative property of addition. This is because commutative property just means doing the operation in anyway and getting the same

result.

3) Answer is b/-a because multiplicative inverse is multiplying numbers(specificly fractions) and get 1 as the result.

eg. Multiplicative inverse of the following are:

A) 1/5=5/1

B) -444446/58=58/-444446

Hope this helps you.
