As a fraction
15/60
We now look to cancel down/reduce.
So we need to find a common factor.
'2' is NOT a common factor because '15' is an 'odd' number, and will not divide by '2'.
So try '3'.
Yes!!! '3' is a common factor ; 3 x 5 = 15 and 3 x 20 = 60
So cancel down/reduce by '3'
15/60 = 5/20
Again we repeat the process.
'2' is NOT a common factor
'3' is NOT a common factor
So try '5'
Yes!!! '5' is a common factor ; 5 x 1 = 5 and 5 x 4 = 20
So cancel /reduce by '5'
5/20 = 1/4 The answer!!!!
This is '15/60' in its fully reduced form ( 1/4 ; in words one quarter).
However, your arithmetic may be more facile, and you can see that '15' is a common factor to both '15' & '60'. So you can reduce it directly to '1/4'.
NB When cancelling down/reducing fractions us prime numbers to start the reduction process. . There are millions of prime numbers, but star by using ,2,3,5,7,11,13,....
Hope that helps!!!!
9/15 in its simplest form is 3/5
15/19 is already in its simplest form, because '19' is a prime number, and there are NO factors of '19' except '1' & '19'.
15/7 is in its simplest form.
39/45 can be simplified to 13/15.
15/16 is in its simplest form.
15 over 30 in simplest form is 1/2.
9/15 in its simplest form is 3/5
30/16 in simplest form is 15 over 8
11/15
1/7
It is: 9/15 = 3/5
4 over 15 is already in lowest terms.
2x over 15
15/6 = 5/2 = 2 1/2
12/15 = 4/5
13/15
2/15
