Hopes this helps:

Answer:

•ROUND IT OFF
Create zeros.
So 199 becomes 200.

•ROUND THE ORDER OF MAGNITUDE
Round a lot, to the nearest “power ten”.
So 218 comes 100, and 2,180 becomes 1,000.

•SLIDE THE DECIMAL POINT
Compact those zeros created by rounding.
So 200,000,000 becomes 2•10^8 (exponential notation).

•SUBSTITUTE A NUMBER YOU CAN REMEMBER
Instead of rounding, find a nearby number you can remember.
So 218 becomes 222, or 210 or 200, something else easy.

Answer:

Simplify means to make smaller or more simple.

Step-by-step explanation:

You need to make the number which needs to be simplified into a number lower than the original number.

For example:

"4" would simplify to "2"

beace half of 4 is 2. This could further be simplifed as "1" is half of 2.

so if there was a fraction:

4/8

the numerator would simplify to 1 and the denominator would simplify to 2 because whatever you do to the top you must do to the bottom. The numerator stops simplifying at 1 and the denominator stops simplifying at 2

so

4/8 = 1/2
