four hundred fifty-six.
If you mean 4/56 then it is 1/14 in its simplest form
Example: to address 555 Main Street, Apartment 456, Hollywood, California 90027 555 Main St APT 456 Hollywood CA 90027
45.6 = 456/10 = 228/5
456 = 45,600%
456 = 4.56*102
Exactly as you have done in the question.
456 698 in words is four hundred and fifty six thousand, six hundred and ninety eight.
456 Torr is equivalent to 0.601 standard atmospheres. This conversion is done by dividing the pressure in Torr by 760 (the number of Torr in 1 standard atmosphere).
10001/999900
0.456 = (0 x 100) + (4/101) + (5/102) + (6/103)
4.56 = 456%
2445
By adding six zeroes to the end.
four hundred fifty-six.

Standard form is the form you want. 100 = 1, 101 = 10, 102 = 100, 103 = 1000 etc Therefore if you want to write 300000000 in standard form it is 3 x 108 The same thing applies to decimals - 10-1 = 0.1, 10-2 = 0.01, 10-3 = 0.001 etc Therefore if you want to write 0.0000004 in standard form it is 4 x 10-7 Note, that the number you multiply the power of ten to must be between 0 and 10 for example - 45600000 CANNOT be written as 456 x 105 but MUST be written as 4.56 x 107 also 0.00000345 CANNOT be written as 345 x 10-9 but MUST be written as 3.45 x 10-7.
