Question

Name the multiplicative inverse of each number:

2

4/5

multiply rational numbers. Find each number:

(-6)(7)

4/3(-3/4)

Answer 1

Multiplicative inverses are found by flipping fractions.

2 is actually 2/1 so it becomes 1/2.   You can do the other one. :)

Mutliplying rational numbers requires multiplying the top across then the bottom.

(4/3)(-3/4) = (4*-3)/(3*4), which you can finish.

Answer 2

Name the multiplicative inverse of each number:

2    = 1/2

4/5=5/4

multiply rational numbers. Find each number:

(-6)(7)=-42

4/3(-3/4)= -1
