How do you write 72.5% as a fraction in simplest form

Answers

Answer 1

Answer:

The 72.5% as a fraction in simplest form is (29/40)

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have to write 72.5% as a fraction in simplest form.

So we put 72.5 over 100

That is (72.5/100)

Now multiply the top and the bottom by 10 to get rid of the decimal, giving;

725/1000

Then divide the top and bottom by like factors,

5 (145/200)

Then another 5,

29 over 40 (29/40)

Hence, the 72.5% as a fraction in simplest form is (29/40)

Answer 2

Answer: So you put 72.5 over 100 (72.5/100)
Then you multiply the top and the bottom by 10 to get rid of the decimal, giving you 725/1000
Then you divide the top and bottom by like factors, starting with 5 (145/200)
Then another 5, giving you 29 over 40 (29/40)

A college student realized that he was spending too much money on fast food. For the remaining 5 months of the year his goal is to spend a mean of $50 a month towards fast food. How much can he spend in December, taking into consideration that in the other 4 months he spent $100, $25, $80, and $30, respectively? Round your answer to two decimal places, if necessary.

Answers

Answer:

The college student can spend $15.00 in December.

Step-by-step explanation:

This can be calculated as follows:

Let y represents the amount to spend in December.

The can now us the formula for calculating a mean is as follows:

Mean = Sum of montlhy spending / Number of months ...... (1)

From the question, we have:

Mean = $50

Sum of monthly spending = $100 + $25 + $80 + $30 + y = $235 + y

Number of months = 5

Substituting the values into equation (1) and solve for y, we have:

$50 = ($235 + y) / 5

$50 * 5 = $235 + y

$250 = $235 + y

$250 - $235 = y

$15.00 = y

Therefore, the college student can spend $15.00 in December.

Final answer:

To achieve a mean expenditure of $50 per month on fast food across 5 months, the student can only spend $15 in December, considering that he has already spent a total of $235 in the other 4 months. This keeps his total spending at $250, giving an average of $50 per month.

Explanation:

The student wants to spend a mean of $50 per month on fast food for 5 months. In 4 of those months, he has already spent $100, $25, $80, and $30, respectively. That totals to $235 in spent funds already. Since the goal is a $50 monthly average, we multiply $50 by 5 months to get a total desired spending of $250. To find out how much he can spend in December, we subtract the total already spent from the total desired spending. As such, he can spend $250 - $235, which equals to $15 in December.

Answers

A mother kangaroo is unhappy when it rains because it can harm her offspring.

Why does rain make a mother kangaroo unhappy?
