10 thousandths or 1/10000 is written as 0.0001 as a decimal.
10^-1 = 0.1
1/5 = 2/10 = 0.2
In standard form it is 1*10^1.
You could write it as 10^1.
10-6 = (1/10)6 = 0.000 001
72 and 1/10 as a decimal is 72.1
10 million is 10 to the 6th power. When you raise it to the power of 10 you are making it 10 to the 6x10th power i.e. 10 to the 60th power. to write it out you would write a 1 followed by 60 zeros before any decimal point.
10 thousandths or 1/10000 is written as 0.0001 as a decimal.
To write 10 billionths in decimal form, you would start with the number 0.000000001. This is because a billionth is one divided by one billion, which is represented as 1/1,000,000,000 or 0.000000001 in decimal form.
For a negative power of -k, the equivalent decimal is the decimal point followed by (k-1) zeros followed by 1.Thus 10^-5 = 0.00001
1 x 10^-9
1 and 8/10 = 1.8
point 1 .1 or.10
10/1000 = 1/100 = 1 ÷ 100 = 0.01
10^-1 = 0.1
1/5 = 2/10 = 0.2
