Use the example below to explain where the decimal point should be placed in the product. Next, explain how estimation can be used to check your answer. Ex: 25.5 x 0.81 =

Our estimation was correct. Look below for explanation.

The decimal place should be shifted to 3 places to decimals to the left because 25.5 has been shifted one decimal place to the left and 0.81 has been shifted 2 decimal places to the left.

Now, to check our answer, you can use 3 ways.

I am going to solve using the option 3.

With that, our estimation was correct. The answer has 3 decimal places.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
