Yes.
42/14 = 3
15/42 15 and 42 can both be divided by 3. 3 x 5 = 15 and 3 x 14 = 42 . 5 and 14 do not have any common factor. Therefore, the simplest form for 15 over 42 would be 5 over 14.
You change it into a fraction form ( 42 over 100) and reduce.
It reduces to 3/14
42/45 = 14/15
6/7
Yes, it reduces to 2/5
30/42 = 15/21 = 5/7
84/90 Since both numbers are EVEN, then cancel down (reduce) by '2' Hence 42/45 Cancel down by '3' The next prime number ,and a factor of both '42' % '45'. 14/15 The answer!!!!!
no
15 will go into 42 two times with 12 left over.
15 over 25 reduces to 3 over 5
