A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 1215, exactly as in the question.
Divide the percentage by 100: So 1215% = 12.15
0.1215 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. Its rational equivalent is 1215/10000 which can be simplified. However simplification would mean that you could lose information about the precision of the fraction.
√1215 = 34.856850116
1215 = 12150/10
1215 - 789 = 426
Divide the percentage by 100: So 1215% = 12.15
12/15 = 0.8
It is simply: 1215.0 but if you mean 12/15 then it is 0.8
It was signed in the year 1215 by King John.
1215, 405,243,135,81,45,27,15,9,5,3,1
94% of 1,215= 94% * 1215= 0.94 * 1215= 1,142.1
1215 is greater.
√1215 = 34.856850116
0.1215 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. Its rational equivalent is 1215/10000 which can be simplified. However simplification would mean that you could lose information about the precision of the fraction.
To express 1215 as a fraction in simplest form, we can write it as 1215/1. Since 1215 and 1 share no common factors other than 1, the fraction 1215/1 is already in its simplest form.
1215 = 12150/10
