How many multiples can a number have?
A number can have an infinite number of multiples since multiples are obtained by multiplying the number by a whole number.
What is the highest power of 25 that divides the product of the first 100 multiples of 5?
The highest power of 25 that divides the product of the first 100 multiples of 5 is 50. This is because for each multiple of 25, we have an extra factor of 25. Since there are 4 multiples of 25 in the first 100 multiples of 5, we have a total of 50 factors of 25.
What is the meaning of the word multiples?
In mathematics, multiples are the result of multiplying a given number by an integer. For example, the multiples of 3 are 3, 6, 9, 12, and so on. These numbers are all obtained by multiplying 3 by different integers. Multiples can be positive or negative, depending on the original number and the integer used for multiplication.
Numbers that are easy to compute mentally?
Numbers like 10, 25, 50, and 100 are easy to compute mentally because they have simple multiples or divisions that are easy to work with. For example, doubling 25 is 50, or dividing 100 by 10 gives you 10. These numbers are often used as benchmarks in mental math calculations.
How validity and reliability can be achieved in selection process?
Validity in the selection process can be achieved by ensuring that the assessment measures what it is intended to measure, using job-related criteria. Reliability can be achieved by designing consistent selection processes that yield similar results upon repeated administrations. This can be done by standardizing procedures, training assessors, and using validated assessment tools.
