Question

Select all that justify the following statement. 8•1/8+(-1)+5=5

A. Commutative- addition
B. Inverse- addition
C. Associative- multiplication
D. Symmetric
E. Commutative- multiplication
F. Associative- addition
G. Inverse- multiplication

Answer 1

The statments that justify this eqaution would be:

inverse - addition

inverse - multiplication

Answer 2

Option A, F and G are correct.

Explanation:

Given the expression

`8.(1)/(8)+(-1)+5=5`

We have to select the statement that justify the above expression.

LHS is

`8.(1)/(8)+(-1)+5`

`\text{Here, }(1)/(8) \text{is the inverse of 8 which is to be multiplied}`

∴ inverse-muliplication

Now, there are 3 terms

1+(-1)+5 which is to be solved

Now, first two are to be added i.e

Associative-addition and commutative-addition takes place.

Hence, option A, F and G are correct.
