I would write is 3.1008 x 1010
But it could be expanded to 3.100809003 x 1010
71.038 in expanded form is.... 70+1+.0+.03+.008
(3 x 10,000,000)+(2 x 1,000,000)+(8 x 1)
Seven hundred and thirty-eight thousandths in expanded form is: 700+ .030+ .008
.008=8/1000
6.458 = (6 x 1) + (4/10) + (5/100) + (8/1000)
In expanded form, 1.008 can be written as 1 + 0.008. This means that 1 is in the ones place, 0 is in the tenths place, and 008 is in the thousandths place. Therefore, 1.008 can be expanded as 1 + 0.008 in numerical form.
3 045 008
.008
8/1000 or .008
You would write eight thousandths as .008
.009 and .008
459.268 = (4 x 100) + (5 x 10) + (9 x 1) + (2/10) + (6/100) + (8/1000)
