3.15 means "three and fifteen hundredths"= 315/100= 33/20
315 = 32*5*7
3.15 x 10^8 will be 315 in decimal form.
It is: 105/64
You can do it in this way, 0.015 = 315/1000200 =3/200
315 million written in standard form is 315,000,000.
315,000,000
315 = three hundred fifteen.
315,000,000

1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
It is: 315 = CCCXV

315 = 32*5*7
Well, it's easier to read, write, and say. For example: if you had the number 315, you know what it is right away. But, if standard form wasn't used, then you would have to say: 300+10+5 which is harder to read, write, say, and understand. Also, it would be harder for people to solve equations because they're so focused on how to write it that they lose thought to what could be a big find! Who would want to solve: fifty-two+ninety+one hundred sixty-five million, four hundred seventy-nine+x= two hundred? :)
