Answer:
Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter.

Answer:
Step-by-step explanation:
Let x be the percentage then...
Start by dividing both sides by 4:
Simplify the fraction:
Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.
