Divide by moving the decimal point.?

Question

8.9 divided by10 to the second power

Answer 1

Move the decimal two places to the left: .089

Answer 2

Whenever you have dividing by moving the decimal point and 10s to the something power, all you have to do is count how many powers its to and move that many spaces to either the left or the right. If you are multipling, then its the the right, if you're dividing, then move it to the left. In this case, 8.9 divided by 10 to the second power means you need to move the decimal two points to the right since you have two powers. You should get 0.089. It's like multipling 8.9 by 100. Hope this helps!

Answer 3

First you have to know what 10 to the second power is. It's 100. So, there are two zeros with base 10. Then, all you do is move the decimal point 2 places to the left, since you are dividing. When you multiply, you move the decimal point to the right. As a result, you will get 0.089

Answer 4

8.9 goes into 100= 10^2

89 goes into 1000 1 1x89=89 100-89=11
bring down the 0 89 goes into 110 1 89 x 1=89
110-89=21 etc

Whenever you have a decimal such as 8.9 you move it one to the right and since 10^2 =100, the number is 100. So you have to add a zero to equalize the problem

Answer 5

Just move the decimal point to the left the number of spaces equal to the power of 10. In this case the answer is 0.089.

Answer 6

8.9/10^2=8.9/100 move the decimal point 2 spaces to the left
the answer is 0.089

Answer 7

= 8.9 / 100

When dividing by 100 move point 2 places LEFT

Answer = 0.089

Answer 8

whatever the power of ten, that is how many places to the left you must move the decimal. If there is no decimal in the numerator, understand that it is at the end of the number not the front. I have students that mess that up all the time.

therefore your answer would be

0.89
