Question

write the multiplicative inverse of the following (1) - 13/4 (2) 1×-7/5​

Answer 1

Answer:

(i): We know that the multiplicative inverse of rational number 'a' is (\frac{1}{a}

a

1

), such that a \times\frac{1}{a}×

a

1

= 1

Therefore, Multiplicative inverse of -13 is -\frac{1}{13}

13

1

.

(ii): We know that the multiplicative inverse of rational number 'a' is \frac{1}{a}

a

1

such thata\ \times\frac{1}{a}a ×

a

1

= 1

Therefore, Multiplicative inverse of \frac{-13}{19}\ is\ \frac{-19}{13}

19

−13

is

13

−19

.

(iii): We know that the multiplicative inverse of rational number 'a' is \frac{1}{a}

a

1

such that a\times\frac{1}{a}a×

a

1

= 1

Therefore, Multiplicative inverse of \frac{1}{5}\ is\ 5

5

1

is 5

(iv): We know that the multiplicative

Answer 2

Answer:

Step-by-step explanation:

multiplicative inverse means the reciprocal of the no.

1.multiplicative inverse of -13/4= -4/13

2.multiplicative inverse of 1 * -7/5

=multiplicative inverse of -7/5= -5/7
