6.78 x 10-9 in decimal form = 0.00000000678
(move the decimal point 9 places to the left)
9 tenths = 9/10 = 9 ÷ 10 = 0.9
0.0000000013
0.90 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 90/100 which simplifies to 9/10.
0.9 as a decimal and 9 over 10 as a fraction.
0.9 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, being a decimal, there is no simpler form. Its rational equivalent is 9/10 which cannot be simplified.
The number 5.9 is already in decimal form. We know that 5.9 is 5 plus 9/10. The 9/10 is 0.9, so 5 + 9/10 is 5.9 as already written in decimal form.
9 tenths = 9/10 = 9 ÷ 10 = 0.9

To write five and nine tenths in decimal form, you simply combine the whole number (5) with the decimal part (0.9). This gives you 5.9 in decimal form. The decimal point separates the whole number from the decimal part, indicating the place value of each digit.
9/10 = 0.9
