A decimal number is simply a way of representing a number in such a way that the place value of a one is ten times that of a one in the place to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So the decimal for 180 is 180 – as in the question.
.004
400.0000.... (as many more zeroes as you want)
400 percent = 4.0 or 4/1
7000 + 400 + 30 + 0.2 + 0.05
25 over 400 as a decimal = 0.062525/400:= 25 ÷ 400= 0.0625 in decimal
2.2222
400% = 400/100 = 4 in decimal form
400 in decimal form = 400.0
To write 180 in scientific notation, move the decimal point after the first digit, giving you 1.80. Then count the number of places you moved the decimal point. In this case, you moved it two places to the right. Finally, express the number 180 as 1.80 x 10^2 in scientific notation.
180/400 x 100 = 45 percent.
