Hey there!
When we multiply fractions and whole numbers, we simply take that whole number and put it over them, and just multiply across. That gives us:

Notice how it's four, because when we have a fraction, we divide. 8 divided by 2 equals four. Next:

4/4 is equal to 1 because 4 divided by 4 is one. 4 goes into 4 once. Next, we have:

That's because 6/3 = 2.
Hope this helps!

Answer:
The temperature would be 55 degrees fahrenheit
Answer:
The potential energy of the ball having 2kg mass would be
J
Step-by-step explanation:
I am assuming the ball has a mass of 2 kg, as you have not mentioned the mass of a ball.
Considering the formula for calculating the gravitational potential energy

As
kg
Acceleration of gravity = g = 9.8 
As the ball is on the height = h = 20 meters
So,

J
Therefore, the potential energy of the ball =
J
