Answer: Fractional form of 2.5 is 5/2. For the removal of the decimal, we multiply and divide by 10. And we get, 2.5/1 x 10/10 = 25/10 = 5/2.
and in ratio answer is 1:40.
The number 2.5 is a mixed number, which means it is a combination of a whole number and a fraction. When written as a fraction, it would be expressed as 25/10. The number 2.5 can also be represented as a decimal, which would be 0.25 when expressed in decimal form.
Answer and Explanation: No, 2.5 is not a whole number since it contains a decimal. Another way of writing 2.5 is 2 1/2. The two closest whole numbers to 2.5 are 2 and 3.
Answer: 2.5% as a decimal is 0.025.
In general, x% is represented as x/100.
The answer is 1.25. This problem asks us to take our number (2.5) and halve it into two groups, giving the answer as the value of one of the groups. Since our starting number has a decimal point in it, we will stick with decimals to be consistent.
All decimals can be converted to fractions. The decimal 2.5 is equal to the fraction 25/10. By definition, a rational number is one that can be written as a fraction or ratio between two integers (whole numbers). Since 2.5 can be written as the fraction 25/10, and both 25 and 10 are integers, 2.5 is a rational number.
The nature of rounding
In common, or 'arithmetic' rounding, it is clear that 2.1, 2.2, 2.3 and 2.4 round to 2.0; and 2.6, 2.7, 2.8 and 2.9 to 3.0. That leaves 2.5, which is no nearer to 2.0 than it is to 3.0. It is up to you to choose between 2.0 and 3.0, either would be equally valid.
Solution: 2.4 as a fraction is 12/5.
Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B. For example, if A is five and B is 10, your ratio will be 5/10.
Ex: If 5 is divided by 2, the answer is 2.5 which is not a natural number. Natural numbers satisfy commutative law for addition and multiplication.
If written in decimal notation, a rational number ends with a finite number of digits to the right of the decimal point, or they can have repetitive digits to the right of the decimal point. 2/5 and 2/3 are rational numbers.
For example 2.5 is a rational number because it can be expressed as 25. Whereas a whole number is a positive number without a fraction or decimal.
So 250% must be 2.5 as a decimal, but there is likely an infinite number of ways to describe it as a fraction- so I only gave a few.
25% is smaller than 2.5. 25% = 25/100 = 1/4.
Answer: Fractional form of 2.5 is 5/2.
For the removal of the decimal, we multiply and divide by 10. And we get, 2.5/1 x 10/10 = 25/10 = 5/2.
The 2.5 percent of 100 is 2.5. The percentage can be understood with a simple explanation. Take 100, and divide it into 100 equal parts.
Both 1.5 and 2.5 are rounded to 2 . 3.5 and 4.5 are rounded to 4 .
For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4)
