Well, adding x10 is scientific notation. Example:456-4.56x102. this is because there are two numbers before the decimal. another example:14945-1.4945x104. if you do not get it, I'm sorry. This is the best i can explain
Assuming one billion is equal to one thousand million, 456 million is equal to 456/1000 = 0.456 billion.
456 yards = 0.259 miles
Expanded Notation of 456 = (4 x 102) + (5 x 101) + (6 x 100)
2445
456 miles
1 mile = 5,280 feet456 miles = (456 x 5,280) = 2,407,680 feet
If you run at 7.6 miles per minute, that is equivalent to 456 miles per hour.
456 million
733.861
By adding six zeroes to the end.
456 miles
