Is 38/53 in simplest form? Explain why or why not. If not, write it in simplest form.

Please help I don't understand this

since 38 and 53 have no common factors, it is in simplest form.

38/54 would be 19/27 in simplest form, after eliminating the common factor of 2 in top and bottom.

To reduce a fraction to lowest terms, you look for a common divisor

for both the numerator and the denominator,
e.g.
45/72
= 5*9/(8*9)
divide both top and bottom by 9 to reduce it to 5/8

In your case of 38/53, since 53 is a prime numbers, it has not
factors other than 1 and itself,
it is reduced to lowest terms
