Berpa jam yang harus di tempuh keretapi dengan kecepatan 70km dengan panjang jalur 560 km
Answer (5)
n=25/99
99n=25
100n-n=99n
Therefore:
100n-n=25
100n=25+n
100n=25.00+0.25...
100n=25.25...
n=0.252525252525......
Find the denominator of 25/99 in its lowest form.
The greatest common factor (GCF) of 25 and 99 is 1. Convert 25/99 to its simplest form by dividing the numerator and denominator by its GCF:
25 ÷ 1
99 ÷ 1
=
25
99
Thus, the denominator of 25/99 in its lowest form is 99.
Find the prime factors of the answer in Step 1.
The prime factors of 99 are all the prime numbers that you multiply together to get 99. The prime factors of 99 are:
3 x 3 x 11
Determine if 25/99 is terminating
A fraction is a terminating decimal if the prime factors of the denominator of the fraction in its lowest form only contain 2s and/or 5s or no prime factors at all. This is not the case here, which means that our answer is as follows:
25/99
= non-terminating ;
The fraction 99 25 converts to the decimal 0.252525... , which is a repeating decimal. This means the digits '25' continue indefinitely. Therefore, it is expressed as 0.25 25 .
