Q-1: Fill in the blanks $\blue\downarrow$

a. The additive inverse of -128 _________.

Ans. The additive inverse of -128 is +128.

Because (-128) + 128 = 128 + (-128) = 0.

b. The value of (9/100)0 is _________.

Ans. The value of (9/100)0 is 0.

Because $\bf\bigg(\frac{9}{100}\bigg)$ = $\frac{9}{100}\times\:0$ = 0 . We Always multiply zero the result is zero.

c. -90 = 6 × ________.

Ans. -90 = 6 × -15.

let the number be x.

$\bf {- 90 \: = \: 6 \: \times \: x} \\ \bf{\frac{6}{x} = - 90} \\ \bf {x \: = \: \cancel \frac{ - 90}{6}} \\ \bf {x \: = \: - 15}$

d. If a number is greater than 1, its reciprocal is ______ 1.

Ans. If a number is greater than 1, its reciprocal is less than 1.

For example let the number be 5 then it's reciprocal $\bf\frac{1}{5}= 0.2$

e. Fraction = _______.

Ans. Fraction = $\bf\frac{P}{q}$.

Because fraction is expressed in the form of $\bf\frac{P}{q}$. For example , $\bf\frac{5}{7}$. $\bf\frac{5}{7}$ is expressed in the form of $\bf\frac{P}{q}$.

f. Two types of integers are _________ and _________.

Ans. Two types of integers are positive integers and negative integers.

Positive integers - Positive integers are those interested which expressed the plus sign (+). For example, $\bf\frac{3}{8}$.

Negative integers - Negative integers are those integers which expressed the minus sign (-). For example, $\bf\frac{-3}{8}$.
