Question

what is the multiplicative inverse of the product when 13 by 15 is multiplied by the multiplicative inverse of 19 by 21​

Answer 1

Answer:

Answer is 95/91

Step-by-step explanation:

Hope this may help you

13/15

&

Multiplicative inverse of 19/21 = 1 /(19/21)= 21/19

Now Multiply them

13/15 × 21/19

(13×21)/(15×19)

= 273/285

=91/95

According to Question

we have to find Multiplicative inverse of the product .

so Multiplicative of the product is

1/(91/95)

=95/91
