(32) / (100)
0.32 or 8/25
(b):
0.8 x 3/5
8/10 x 6/10
(8 x 6) / (10 x 10)

<u><em>Answer: x=6 *The answer should be the positive sign.*</em></u>
Step-by-step explanation:
division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
divide by -8 both sides of an equation.
-8x/-8=-48/-8
48/8=6
48/6=8
8*6=48
x=6
Hope this helps!
Thanks!
Have a great day!
