Answer:
3.98 x 10^7
Step-by-step explanation:
The two numbers are very near 7200 and 300. The sum of those is a good estimate of your sum:
... 7200 + 300 = 7500
_____
If you're taught methods of addition that include "make a ten" or "make a hundred", you know you can "borrow" a 1 from 7203 (making it 7202) and loan that 1 to 299 to make it 300. Now, you know your sum is exactly 7202+300 = 7502, with no estimation necessary.

Answer:
Multiplying any number by .25
Step-by-step explanation:
This is dependent on what number you are trying to find.
To find 25% of a number; multiply the number by .25 (This is most common)
To find a 25% discount; multiply by .25 then subtract that number from the original number (e.x. 100 x .25 = 25 then 100 - 25 = 75)
These are the two most common, if there is another way you are trying to find feel free to comment, or shoot me a message. I am happy to help!
