"5" is already a decimal number. You could also write it as "5.0". A decimal is a whole number in the decimal (base-10) number system or a proper fraction whose denominator is a power of 10. Decimal numbers are written by convention with the whole-number part to the left of a "decimal point" (.) and the fractional part to the right. Either or both the whole or fractional part may be zero (0).
To write 28 10 as a decimal, you divide 28 by 10. The quotient is 2.8, so 28 10 expressed as a decimal is 2.8.

0.4
As a fraction, you can write it as 8/10. As a decimal, you can write it as 0.8.
Write the five as the whole number before the decimal point then divide the numerator (eight) by the denominator (ten) of the fraction and put it after the decimal point: 58/10 = 5 + (8 ÷ 10) = 5.8
