Let r1 and r2 be the "divides" and "is a multiple of" relations on the set of all positive integers, respectively. thatis, r1 ={(a, b)|adividesb}andr2 ={(a, b)|a is a multiple of b}. find

a. r1 ∪r2.

b. r1 ∩r2.

c. r1 −r2. d)r2−r1. e)r ⊕r. 1 2

i'm not sure i quite understand, could you provide more information?

answerthe vertex form

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
