how can you find the product of positive and negative decimals

Answers

Answer 1

(I have attached an example for reference)

1) Product means multiply, so we will multiply the decimal numbers.

2) First multiply both the numbers just the way you multiply two whole numbers.

3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.

4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.

5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

The answer is 14 because -2 x -7 = 14. If you didn’t already know a sum is the value given when two or more numbers are multiplied together and the reason -2 and -7 multiply to get 14 is because the negatives cancel each other out to create a positive.

it’s just -9 since 2 + 7 is 9, but they’re opposite signs so it’ll be (-2) + (-7) = -9. The signs don’t change since both numbers are negative

The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?

₋₋₋₋₋₋₋₋ °F per hour

Answers

Answer:

-3.5

Step-by-step explanation:

As there was a total change of -21, that would be the first part of your equation:

-21

As 6 hours had passed and you are trying to find the mean, your equation would now be:

-21 ÷ 6 = ?

Now you can solve the equation, and the answer is -3.5°F per hour.

The mean change in temperature per hour is -3.5 °F.

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The total change in the outdoor temperature over 6 hours was -21°F

So, in one hour the mean change in temperature

= -21/6

= -3.5 °F

Hence, the mean change in temperature per hour is -3.5 °F.

Find the answer and simplify.
What is (4/9)^2?
What is 4 over 9(as a fraction) to the power of 2?

Answers

Answer:

16/81

Step-by-step explanation:

To square a fraction, you would have to square both the denominator and the numerator. You would have to do 4x4/9x9, which is 16/81.

Answer:

The answer is 16/81

Step-by-step explanation:

To evaluate this equation first find a understanding of what needs to be solved.

Here we see that we need to solve 4/9th to the power of 2.

to solve this we find what 4 to the power of 2 is and what 9 to the power of 2 is.

To use the power of 2 you multiply the number to itself that many times so if its 5 to the power of 3 you would right it as 5 x 5 x 5.

In this case we need to do 4 x 4 and 9 x 9.

4 x 4 = 16

9 x 9 = 81

The 4 x 4 solution remains as the numerator

The 9 x 9 solution remains as the denominator

After solving we get 16/81, due to the 81 not being even and 16 not being a multiple we can not simplify this fraction anymore.

The correct answer is 16/81 have a great day :)
