I'm assuming the goal of this style of division is to divide by whole numbers instead of decimal numbers. In that case, you would need to move the decimal in the divisor and the dividend three places to the right.

Step-by-step explanation:

Why don't we see the ground coming toward us? We have less gravitational force than the earth. ... It has a lot of mass, so it feels the earth's gravitational force less than smaller objects do. It has more mass than the earth, so it stays in one place while the earth orbits it.

Your restaurant bill is $42.16. You want to leave a 20% tip. What is your best
estimate of a 20% tip?
Your answer

Answers

Answer:

$8.40

Step-by-step explanation:

Since this is an estimate, you need to do it in your head. The way I did it was I divided 40 by 5 since 20% is one fifth of 100%, then I divided 2 by 5 and added them together which equaled 8.40.

Answer:

About $8

Step-by-step explanation:

Move decimal point one place to the left (making $4.20), then double that answer (making $8.40). You said estimate so I rounded down to $8 but a more precise answer would be $8.40.

Step-by-step explanation:

If you're distributing each value, I would recommend you to use the lattice method so that you can work on it faster. Make sure to add the exponents instead of multiplying to have an accurate answer. Once your done then cross out the ones that would subtract to 0 which would leave you with [tex]m^{4\\}[/tex]+[tex]m^{2}[/tex][tex]n^{2}[/tex]+[tex]n^{4}[/tex] as your final answer if you did it properly.
