Need help to explain to my daughter:
A horsepower is the power needed to lift 33,000 pounds 1 foot in 1 minute. It is equivalent to 746 watts. Express 525 watts as a portion of a horsepower both as a fraction and a decimal rounded to the nearest thousandth.
Thanks for anyone's help!!!
power= 525/746 hp
then for decimal, divide 525 by 746.
thanks.
Sure! I'd be happy to help you explain this concept to your daughter.
To calculate the fraction of a horsepower, we need to find out how many watts make up one horsepower. We know that one horsepower is equivalent to 746 watts. So, we can set up the following equation:
1 horsepower = 746 watts
To find what portion of a horsepower is represented by 525 watts, we will set up a proportion:
525 watts = x horsepower
Now, let's solve the proportion:
525 watts / 746 watts = x horsepower / 1 horsepower
By cross-multiplying:
525 = 746 * x
Divide both sides of the equation by 746 to solve for x:
x = 525 / 746
Now, let's express this as a decimal rounded to the nearest thousandth:
x = 0.703
Therefore, 525 watts is approximately equal to 0.703 of a horsepower.
To express it as a fraction, we can write:
x = 703/1000
So, 525 watts is approximately equal to 703/1000 of a horsepower.
