7/10=10/7

1/2=2/1

5=1/5

1. Number 7/10 Reciprocal 10/7 Number 1/2 Reciprocal 2/1 Number 5/1 Reciprocal 1/5

2. 5/8 x 3/2= 15/16

3. Sorry I can't do a model

Step-by-step explanation:

The Reciprocal  is the number but opposite and 5x3 is 15 and 8x2 is 16 so 15/16

15x = -75

x = -5

Step-by-step explanation:

Set the first part about the product of 15 and x equal to -75.

Then, divide both sides by -15 to get y = -5.
