Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form as: 20.007
7 ten thousandths in standard form is written as 0.0007.
.0007
4.007
Twenty-seven thousandths (0.027) in standard form is: 2.7 × 10-2
7+0.05+0.33+1000
They are: 5/1000 = 5.0*10-3 and 7/1000 = 7.0*10-3
20 and 7 thousandths = 207/1000 = 20.007 = (2 x 10) + (0 x 1) . (0/10) + (0/100) + (7/1000)
20 + 7 + 09 + 001 = 37
8.0026
70 thousandths = 0.070 Although, its value is the same as 7 hundredths, 70 thousandths implies a greater degree of accuracy so the number SHOULD have a zero at the end.
3.0020704007x1010
In standard form, it is 2.3064907*10^7.
