The multiplicative inverse of a nonzero rational number a/b is?

Question

Im only in 8th grade, so please dont make the answer complicated...thanks!

Answer 1

well, a multiplicitive inverse means that when you multiply both numbers together they equal one,

so if you have a/b, and you multiply it by b/a, you notice by your multiplication rules your new fraction is
ab/ba, and we know that ab=ba, so the top and bottom cancel, and you get one, so the multiplicative inverse of a/b is b/a

hope that helped you

Answer 2

b/a

Multiplicative inverse just means the reciprocal -- or in other words, flip the fraction.
