The product of -9/17 and its reciprocal​

The product of any number and its reciprocal is always 1

Step-by-step explanation:

Example:

The reciprocal of a number 'a' is '1/a'.

Therefore, the product of 'a' and its reciprocal gives:

=a × (1/a)

=a/a

=1

the product of -9/17 and it's reciprocal will be 1

maybe i can

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
