2)a,b,d

3) b, d

Answer 2

☯ AnSwEr :

(1). Additive inverse : In additive inverse the sign of the number is changes. Such as if it -1 then additive inverse of -1 will be 1.

In the Question, Option d is correct because -25/-52 = 25/52 and the additive inverse of 25/53 will be -25/52.

So, Option D is correct.

(2). Reciprocals : Reciprocals means the opposite number,i.e., numerator will take place of denominator and denominator will take place of numerator.

In this question, Option a is the correct because in all the questions there is negative sign in all options but not in first one.

So, Option A is correct.

$\rule{200}{1}$

(3). Multiplicative Inverse : In this the number got reciprocal of the number.

In this question, Option b is correct because -3/5 * 8/11 = -24/55 and it's multiplicative inverse will be 55/-24

So, Option B is correct.

$\rule{200}{1}$

(4). Rational Numbers : Rational numbers are tgise number which are in the form of p/q where p and q are integers.

In this question, Option d is correct beacause rational numbers can't be negative.

So, Option D is correct.

$\rule{200}{1}$

(5). Uf we multiply the denominater by 9 then our denominator will bacome 162(18 * 9). So, we will also multiply numerator by 9.

Numerator = -16 * 9 = -144

So, Option D is correct.

$\rule{200}{1}$

(6). If we multiply numerator by 13/5 then our numerator will became 65 (25 * 13/5. So, we will also multiply denominator by 13/5.

Denominator = 35 * 13/5 = 105

So, Option B is correct.

$\rule{200}{1}$

(7). A rational number can be expressed as a terminating decimal if its denominators factors are 2 and 5.

So, Option D is correct.

$\rule{200}{1}$

(8). The product of -2/5 and -4/5 is -(-8)/25 = 8/25

So, Option C is correct.

$\rule{200}{1}$

(9). The sum of -4/5 and 14/5 = -4 + 14/5 = 10/5 = 2

So, Option B is correct.

$\rule{200}{1}$

(10). The number of rational numbers between -1 and 1 is infinite because if we will multiply both by onfinte then our answer will be infinite.

So, Option B is correct.

$\rule{200}{1}$

(11). Multiplicative Inverse : In this the number got reciprocal of the number.

The multiplicative inverse of 0/1 is 1.

So, Option D is correct.

$\rule{200}{1}$

(12). Value of 1/3 - 2/3 = 1 - 2/3 = -1/3
